Small driftwood I found at the beach. The 1-yen coin is not included and is for size comparison only. This is a natural item, so there may be sand, chips, cracks, etc. Please refrain from purchasing if you are concerned about these imperfections. I have lightly rinsed off the sand and dried it in the sun. If you intend to use it in an aquarium, terrarium, etc., please boil it and remove any tannins yourself. I have not confirmed if it sinks. Please use it in aquariums and terrariums at your own risk.
