I found these at the beach near my home (^^) This is a set of 22 long, thin pieces of driftwood! The first photo shows everything. They haven't been treated to remove tannins, but they have been: Washed with water and a brush → dried in the sun → brushed. ⚪︎ Although they have been lightly cleaned, there may be some remaining dirt, sand, or mold that couldn't be completely removed. ⚪︎ If you intend to use these for living organisms, please clean and remove tannins before use. ⚪︎ They will be put in a bag and shipped in a Takkyubin Compact box. ⚪︎ There may be some breakage, chipping, or peeling of the surface during transport. Instant purchase is OK!
