Thank you! These are small apple tree branches from the natural bounty of Iizuna, Shinshu (^_^) They are branches pruned in February. They are quite dry. By chewing on them, small animals can prevent their teeth from overgrowing and relieve stress. Also for dogs (^_^) When shipped, they may have some moisture from the fresh wood. Upon arrival, please take them out of the bag and store them without sealing them, such as 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. Diameter: 10-15mm 30 pieces Branch length: 10cm Since they are handmade, the lengths may vary slightly, please understand. m(._.)m
