Thank you! These are small apple twigs from the natural bounty of Iizuna, Shinshu (^_^) They are branches pruned in February. They are dried. Short size. By chewing on them, small animals can prevent overgrowth of their teeth and relieve stress. When shipped, the wood may be slightly damp. Upon arrival, please remove them from the bag and store them unsealed in a basket or vegetable net. Some may have white fuzz from budding, but it is not mold, so please feel free to give them to your pet. m(._.)m Pesticide-free. 5mm diameter. 320 pieces. Branch length: 5cm. Please understand that the length may vary slightly due to being handmade. m(._.)m
