A tua merch is a platform that helps creators design and offer their own personalised merchandise. Its central idea is simple: creators can put their own designs on carefully selected products and build a collection that reflects their work. The catalogue includes textile items such as T-shirts, tote bags, hoodies, sweatshirts and jackets, alongside stationery and ceramic products, including notebooks, calendars and mugs. Visitors can browse merchandise from featured creators, discover their collections and explore the wider range of available products.

The site invites new creators to get involved and presents a straightforward process for starting a merchandise range, while also showcasing existing participants such as Manaia and Livra-te. It reports 18 creators, 100 products for sale and 1,500 product varieties in its catalogue. A tua merch also provides customer support information, including details about returns and exchanges, frequently asked questions, and privacy and cookie policies. The brand describes its venture as a partnership with Cor Sem Fim, bringing together creators and custom merchandise in one place.
