“Where fun meets sustainability”: Olivia and Carolina, two very young sisters from Barcelona, chose to put this vision into practice by launching Oli&Carol, a line of toy accessories for little ones made entirely from natural rubber. In addition to being handcrafted and hand-painted with natural pigments, they are completely plastic-free. Respect for the environment and strong attention to hygiene define the collection: from banana-, apple-, or lemon-shaped pacifier holders, to watermelon slice, carrot, or radish teethers, and even artichoke- or cauliflower-shaped rattles. Oli&Carol objects are small in size but big in meaning: their ergonomic shapes and bright colors stimulate curiosity and the desire to explore. At the same time, they are a playful tribute to the world of nature and ecology.
