The creative souls behind Oli + Carol are sisters Olimpia and Carolina, who decided to start a business based in Barcelona two years ago. They both love design and nature and wanted to create environmentally friendly products in a fun business. Oli + Carol toys are made out of 100% pure rubber from Hevea trees, all in one piece with no holes to let water come inside. They are perfect for soothing gums, and are hygienic, safe to chew, and biodegradable. They can be used as teethers, bath toys, decorative objects and more.
