Trocaí helps collectors mark the stickers they own, find people with the ones they need, and arrange exchanges.

Landing page captured for the 2026-08-24 issue.

Field notes

The exchange begins with an inventory: collectors mark owned stickers and expose the gaps in their albums. The service then looks for reciprocal matches, pairing a needed sticker with a duplicate the other collector wants, before handing the conversation to WhatsApp. The current edition is built around 980 stickers from 48 selections, while the site says the same model could later cover bands, anime, superheroes, and other collections.
