All ZK Merch products are made to order. Please allow 2–5 business days for most UK orders. This allows enough time for production, plus additional time for shipping. You'll receive an email as soon as your order is dispatched.

Yes! We offer worldwide shipping on some stores. International delivery times vary by destination, and you may be responsible for customs or import fees. If the option for international delivery isn't showing at checkout, the the brand store you are shopping on doesn't currently support it.

As all items are custom-printed to order, we’re only able to accept returns for damaged, faulty, or incorrect items. Please report any issues within 7 days of receiving your item.

You’ll receive a notification email once your order has been shipped. We do not send a tracking link. If you haven’t received your order within 5-10 working days, contact our support team.

Most product pages includes a size guide. We offer a wide range of sizes, but availability may vary depending on the design, brand or garment style.
