Instant purchase OK. This is a set of 10 pieces, approximately 16-37.5cm in length. How about using them to plant plants by making holes? I took photos of the front and back of each driftwood piece. I picked them up at a nearby beach. I cleaned them with a brush, soaked them in hot water (and left them for more than 15 hours to remove the astringency), and then dried them in the sun. There may still be some sand and wood chips that I couldn't remove, so please understand. I will send them via Mercari Takkyubin (courier service) without any protective material. There may be cracks or chips during shipping, so please be aware of this. I have not treated them for use with living creatures, so please use them at your own risk. I think they are fine for planting plants. I have many other driftwood pieces for sale, so please take a look. No discounts, sorry. Discounts are available for multiple sets purchased.
