Thank you! These are small apple twigs from the natural bounty of Iizuna, Shinshu (^_^) They are completely dried. Short size. By chewing on them, small animals can prevent overgrowth of their teeth and relieve stress. When shipped, they may have some moisture from the fresh wood. Upon arrival, please take them out of the bag and store them unsealed in a cage 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: 5-10 mm 220 pieces Twig length: 5 cm Please understand that the length may vary slightly due to being handmade. m(._.)m
