I found these at a beach near my home (^^) It's a set of 12 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, then dried in the sun, and brushed. ⚪︎ Although they have been cleaned, there may be some remaining dirt, sand, or mold that couldn't be completely removed. ⚪︎ If you plan to use them for living organisms, please clean them and remove tannins before use. ⚪︎ They will be packed in a box as is. ⚪︎ There may be breaks, chips, or peeling of the surface during transport. Instant purchase is welcome!
