Thank you! These are small apple twigs, a gift from the natural bounty of Iizuna, Shinshu (^_^) Freshly cut, live branches from the October pruning. Short size. By chewing on these, small animals can prevent overgrowth of their teeth and relieve stress. The short size makes them easy to hold and gnaw on. When shipped, the fresh wood will be damp. Upon arrival, please remove them from the bag and store them unsealed in a basket or vegetable net. Some twigs may have white fuzz, which is new growth and not mold, so you can give them to your pet with confidence m(._.)m Pesticide-free. Diameter: 2-5 mm 160 pieces Branch length: 5 cm Please note that the length may vary slightly due to hand processing m(._.)m
