This is Beta Chip (wood chips) for laboratory animals. I used it as bedding for my hamster, but it passed away, and I kept the leftover material at home. I am listing it because I have no plans to use it. There is about 1 kilogram remaining. (This is an approximate weight as I measured it on a human scale with the cardboard box.) How about using it as bedding for hamsters and guinea pigs, or as a play area for rabbits and chinchillas? Here it is: https://www.jax.or.jp/product-and-service/equipment/bedding
