The Guarantee terms applied on the products listed on Twoosk Marketplace are provided by the Marketplace Seller.

Although, the Guarantee period may vary depending on which Seller Shop you are buying the products from, if the item you bought on Twoosk Marketplace turns out to be faulty after delivery or not as advertised (does not match the seller’s description), the Marketplace Seller has to offer you free repair or, at his option, replacement within a period of at least six (6) months following delivery.

When repair or replacement is not possible, the Marketplace Seller may refund you for the item.

To initiate a return request, please send an email to help@twoosk.com. You will need to provide your order reference, let us know the item(s) you wish to return and explain your reason for returning.

Twoosk Customer Care team will intercede with the Marketplace Seller on your behalf. If the Seller accepts your return, you must return the package as per our instructions to the Seller´s warehouse address.

Please note that customers need to cover the shipping fee to return items to the Marketplace Seller. However, this cost may be refundable, if after examining the item the Seller agrees that it was defective when you bought it.

For more information about Twoosk Marketplace Return and Guarantee Policy, please go to section 6 and 7 of Twoosk Marketplace Terms & Conditions.
