I found these at a beach near my home (^^) It's a set of 25 small driftwood pieces! The first photo shows everything. They haven't been treated to remove tannins, but I have: Washed them with water and a brush → Dried them in the sun → Brushed them. ⚪︎ Although I have cleaned them, there may still be some dirt, sand, or mold that hasn't been completely removed. ⚪︎ If you intend to use them for living organisms, please clean them and remove tannins before use. ⚪︎ They will be shipped directly in a Takkyubin Compact box. ⚪︎ There may be some breakage, chipping, or peeling of the surface during transport. Instant purchase is OK!
