I found these at a beach near my home (^^) This is a set of 21 long, thin 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 be some remaining dirt, sand, or mold that I couldn't completely remove. ⚪︎ If you plan to use them for living organisms, please clean them 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 shipping. Instant purchase is OK!
