100% NATURAL RUBBER- 100% TOXIC FREE. Lucas b. Natural Dog Toys are made with 100% natural rubber (latex) from the sap of Hevea Brasiliensis trees. They're free of any harmful chemicals--like BPA, phthalates, and nitrosamines. Each toy is handmade in Morocco, colored with natural, food-based dyes, and then hand-painted by artisans with non-toxic, permanent, certified lead-free paints. In short, they're the safest dog toys on the planet. (They're also made to be really fun--because if your dog doesn't play with them, what's the point?) YOU WOULDN'T CHEW ON THEM, BUT YOU COULD. It might shock you to learn that pet-toy companies in the U.S. don't legally have to abide by any safety standards at all--which means your dog can be exposed to all sorts of harmful chemicals. As dog owners, it certainly shocked us. We wanted something better, which is why we created Lucas b. Our natural dog toys comply with the exact same safety standards as children's toys: European Safety Standard EN 71. (Hey, dogs are family, too!) LUCAS B. AND LANCO. Lucas b. is proud to partner with Lanco, a family-owned business based in Barcelona, Spain. Since 1952, Lanco has been the industry leader in 100% natural rubber toys for both pets and children. Each Lucas b. Natural Dog Toy is handcrafted individually from start-to-finish in Morocco and then quality-inspected in Barcelona. Lanco is dedicated to being an eco-friendly, sustainable, and socially responsible company, promoting gender equality in the workplace (in a country where it's difficult for women to find jobs). We're thrilled to bring these all-natural dog toys to the U.S.!
