Prompt shipping and expert packing

Our long-standing relationship with UPS FedEx DHL and other global carriers lets us offer a range of shipping services. Our warehouse personnel will pack all goods to our exacting specifications. Your items are carefully inspected and secured properly prior to shipping. We deliver to thousands of clients every day from all over the world. This demonstrates our dedication to become the biggest online retailer in the world. Both Europe and the USA have warehouses and distribution centres.

Note: Orders with more than one product are assigned a particular processing time based on the individual product.

We will thoroughly inspect all products before they are shipped. The majority of orders today are shipped in 48 hours. Expected delivery times are between 3 and 7 days.

Returns

The inventory is constantly changing and we cannot control it completely because of the fact that multiple parties are involved, which includes our factory and warehouse. The actual stock levels can fluctuate at any point. It's possible that you may not receive your order once it has been placed.

The policy is for 30 days. If you haven't received the product within the 30 days period, we are not able to issue the option of a refund or exchange.

You are able to return a product when it's unopened and in the same condition as when you received it. It must also be returned in its original packaging.
