Our new bamboo tags are eco-friendly and that is why we are offering them. They come in three different sizes: standard, monster and circle tag. Bamboo is sustainable and made from natural vegetation that grows to maturity in three to five years, far less than the twenty years trees can take. Each tag is individually packed in an environmentally friendly, biodegradable zip-lock bag and includes a free aluminum 24", 30" or 4" made in the USA ball chain.
