Orders are typically delivered within 9 business days after the carrier picks up your package. Delivery times may vary depending on your location and the local carrier handling the final leg of delivery.

You will receive your tracking number by email within 2–5 business days after placing your order. This is the time needed for our warehouse to process, pack, and ship your order. Once shipped, the tracking number is sent automatically.

This is completely normal in the first 1–3 days after you receive the tracking number. It takes time for the carrier system to register and update the tracking information. Please wait a few days and try again. If the issue persists after 5 days, contact our support team.

A delivery failure can occur for several reasons: incorrect address, no one available to receive the package, or a failed delivery attempt by the local carrier. We recommend visiting 17track.net, entering your tracking number, and checking the final-mile carrier details. You can then contact that carrier directly for more specific information about your delivery.

We process orders quickly, so changes or cancellations must be requested as soon as possible. Please contact us immediately via live chat or email. Once an order has been shipped, we are unable to make changes or cancel it.
