I found these at a beach near my home (^^) This is a set of 6 large, horizontally long 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 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!
