Hi, and welcome to veggiewristbands.com. The original place to stock up on your Veggie Wristbands! Thank you for your interest. Green Wristbands - an instantly visible way to show your true colours! Why not show your support & solidarity for a vegetarian or vegan way of life by wearing one (or both) of these identifying bands?! The bands measure about 21cm in circumference. Our wristbands are, of course, completely vegan (silicone oil-based type of rubber!!!), and no animals were harmed in the making of them! No humans were exploited either.
