This is driftwood with holes in it, and it's lightweight. I found it on a nearby beach. I cleaned it with a brush, soaked it in hot water (and left it for over 15 hours to remove the astringency), and then dried it in the sun. I think there may still be some sand and wood chips that I couldn't remove, so please understand. I will send it via Mercari Takkyubin. There may be cracks or chips during shipping, so please be aware of this. I have not treated it for use with living creatures, so please use it at your own risk. I think it's okay to plant plants in it. I have many other pieces of driftwood for sale, so please take a look. I'm sorry, but I can't offer discounts. I will offer a discount if you purchase multiple sets. In that case, please comment before purchasing or request a combined order. #Handmade materials #Ornaments, Interior #Flower gardening #Natural wood
