Redbubble is an online marketplace that allows artists and designers to sell their unique creations on a variety of products. Users can upload their artwork, which can then be printed on items like t-shirts, stickers, phone cases, and home decor. This platform provides a way for independent creators to reach a global audience without the need for inventory or upfront costs. Customers can browse through a vast selection of designs and support artists by purchasing products featuring their work. Redbubble handles the production, shipping, and customer service, making it easy for both creators and buyers to engage in the art community.
