Vinted.es is the Spanish portal for the global leader in the C2C (consumer-to-consumer) online secondhand marketplace. Unlike the other retailers you have inquired about, which sell new items from stock, Vinted is a platform where individuals sell their own pre-loved goods directly to other users.

Vinted.es is primarily known for clothing, footwear, and accessories. It is designed to make the process of clearing out a closet simple and profitable for the seller, while offering buyers a way to find vintage pieces or high-street brands at a fraction of the original retail price.
