Returns

The stock market is always changing. It's not entirely managed by us since we are involved with multiple organizations, such as the factory and our storage. Therefore, the actual inventory could change at any time. Be aware that it is possible for your order to be out of stock after you have placed the order.

Our policy lasts for thirty days. If you haven't received the product within 30 days, we are unable to offer a refund or an exchange.

You can only return a product if it is unused and still in the same state as when you first received it. It should also be returned in the original packaging.
