integer400 is shaped by code, logic, and system thinking. Rooted in XSS hunting, the focus has shifted to translating design into physical goods—from finding vulnerabilities to creating something tangible. Inspired by hacking and programming culture, products feature minimal, text-driven designs reduced to essential signals. No loud graphics. Just subtle statements for those who understand.

FAQ


  • Where is the store based?

    Central Java, Indonesia

  • Do you keep products in stock?

    No — all products are made to order. We partner with Printful (www.printful.com), which means each item is created only after you place an order.

  • Why don’t you keep inventory?

    This approach helps us avoid overproduction and waste, while ensuring every item is freshly made.

  • Can items go out of stock?

    Occasionally, yes. While we don’t hold inventory, our fulfillment partner (Printful) relies on blank apparel suppliers. If a specific size or color is unavailable after you place your order, we’ll offer an alternative or a refund.

  • Will designs always be available?

    Not necessarily. Some designs may be discontinued over time as new releases are introduced.

  • Why would a design disappear?

    Redesigning and rotating styles is a common practice. As new “Coming Soon” products are released, similar or older designs may be removed to make room for updated collections.

  • Will I be notified if a design is discontinued?

    Customers will not receive notifications when a design is removed. So, availability will change without prior notice.

  • Can I still purchase a design that has disappeared?

    Yes, you may request previously removed designs from us. If available, they may be brought back for a limited time upon request.

  • What happens if a product is out of stock after I place an order?

    If a selected product becomes unavailable after your order is placed, we may fulfill it using the most compatible replacement. The replacement will match the original item as closely as possible in terms of style, quality, and color. There will be no additional cost for this substitution. If no suitable alternative is available, we will contact you with available options.

  • Why does your phone case include a Proposition 65 (P65) warning? Is it safe?

    The phone case may contain trace amounts of chemicals listed under California Proposition 65, which requires businesses to provide a warning for even very small exposures. In most cases, the level of exposure is extremely low and considered a small risk, and the product is safe for normal, everyday use. Similar warnings are commonly found on everyday items such as coffee, electronics, furniture, ceramic mugs, and even some clothing—this doesn’t mean they are dangerous, only that the law requires disclosure.

  • Do you accept orders placed outside of the US?

    Yes, we do! Please see the details below:
    1. T-shirts (short sleeve, oversized, and long sleeve): Available for shipping to the US, Canada, Australia, New Zealand, Japan, and Singapore.
    2. Phone Case: US only.
    3. Other items (Sweatshirts, Hoodies, Sweatpants, Shoes, Hats, Mugs): Available in the US and Japan only.

  • Is a phone number required for shipping?

    Providing a phone number at checkout is recommended to help avoid shipping delays. Details are as follows:
    1. Australia, New Zealand, and Canada: A phone number is strongly recommended.
    2. Japan and Singapore: A phone number is often expected by couriers.
    3. United States: Usually safe without a phone number.

    For Australian customers, starting August 4, 2026, Australia Post requires either a valid recipient email address or/and an Australian mobile phone number for delivery.

  • Where do you ship from?

    Your order is produced and shipped from the Printful fulfillment center closest to you whenever possible.

  • Are the prices inclusive of tax, shipping costs, and handling fees?

    Yes. However, the tax included refers to Printful’s tax. We do not collect or remit sales tax to your country.

  • I see a shipping fee of $999,999.00 — is this correct?

    This amount is intentionally set as a placeholder for unsupported regions. It is not a real shipping cost and is designed to prevent orders from being placed from countries we do not currently serve.

  • What happens if I place an order anyway?

    Are you serious? If that happens, all incoming orders are subject to manual review and confirmation. Orders from unsupported countries will not be processed and will be canceled. Any payment made will be refunded in accordance with our store policy.

  • My country isn’t listed — can you ship to me?

    You’re welcome to contact us before placing an order. We may be able to review your request and confirm whether shipping can be arranged.

  • How long will it take to receive my order?

    Production typically takes 2–5 business days. After that, your order is shipped. Estimated delivery times (after production):
    USA: 3-6 business days
    Canada: 2-5 business days
    Australia: 2-5 business days
    New Zealand: 4-7 business days
    Japan: 2-3 business days
    Singapore: 4-5 business days
    Note: These are estimates and may vary due to customs or carrier delays.

  • Will my items ship together?

    Not always. Orders may be fulfilled from different facilities, so items can arrive in separate packages.

  • Can I track my order?

    Yes. Once your order ships, you’ll receive a tracking link via email. Please check your Spam folder in case the email is filtered there. You can also log in to StoreEnvy, go to the My Orders section, and select your order to view its status. If you still can’t find your tracking details and it has been a while since your purchase, please reach out to us.

  • Do you accept bulk or wholesale orders?

    We currently do not accept bulk or wholesale orders. All products are made-to-order and produced individually to maintain quality and consistency with our design standards.

  • Do I have to pay customs fees or import taxes?

    Yes — for international orders, customs duties, GST, VAT, or import taxes may apply. These charges are:
    1. Not included in the product price or shipping cost.
    2. Determined by your country’s regulations.
    3. The buyer’s responsibility.

  • How much will customs fees cost?

    The amount varies by country and order value. In many cases, it ranges roughly between 5%–20% of the order value, but it can differ widely.

  • How can I avoid or reduce customs charges?

    While we can’t guarantee avoidance, you can:
    1. Keep orders below your country’s tax threshold.
    2. Split large orders into smaller shipments (e.g., under $200 USD, where applicable).
    3. Check your local customs rules before ordering.

  • What happens if I don’t pay customs fees?

    If customs fees are not paid:
    1. The package may be held or returned.
    2. Refunds may not be issued for unclaimed items.

  • Will you mark my order as a gift or lower the value?

    No. We follow legal shipping regulations and cannot alter customs declarations.

  • Are there delays due to customs?

    Sometimes. Customs inspections can add a few days to several weeks, depending on your country.

  • Do you accept returns or exchanges?

    Because all items are made to order, we do not accept returns or exchanges for incorrect sizing, change of mind, or buyer’s remorse. Please review sizing, colors, and product details carefully before placing your order. If you have any questions, feel free to contact us — we’ll do our best to guide you.

  • What if I receive a damaged or incorrect item?

    If your item arrives damaged, misprinted, defective, or incorrect, please contact us within 30 days of delivery with:
    1. Your order number.
    2. Clear photos of the issue.
    We’ll arrange a free replacement or refund at no cost to you.

  • What if my order is lost in transit?

    If your order appears lost, contact us within 30 days of the estimated delivery date. We’ll investigate and, if confirmed, send a replacement.

  • Can I return an item if it’s unworn?

    Even if unworn, returns are not accepted unless the item is defective or incorrect. This is because each product is made specifically for your order.

  • Who pays for return shipping?

    For defective or incorrect items: we cover all costs.
    For all other cases: returns are not accepted, so shipping does not apply.

  • What if I entered the wrong address?

    If the shipping address was incorrect:
    1. The order may be returned to the Printful's facility.
    2. Reshipping costs are the buyer’s responsibility.

  • Can I cancel or change my order?

    Orders can only be canceled or changed before production begins (usually within a few hours of ordering). After that, changes are not possible.

  • Will colors or print placement be exactly the same as photos?

    Slight variations may occur due to screen differences, print process, or garment type. These are not considered defects.

  • What if I have a question that isn’t answered here?

    If you couldn’t find the information you’re looking for, feel free to contact us — we’re happy to help. You can reach us anytime via Contact page. We typically respond within a few hours.
