These are pumice stones from Sakurajima, Kagoshima, an active volcano. Carefully selected, these pumice stones have a fine texture and are among the lightest available. They are so soft that fingerprints disappear when touched with bare hands. You can carve them with a carving knife to create your own original pumice stone pots! They are also perfect for removing old dead skin cells! You can also use them for body care. Please share them with your family and friends! Ideal for bonsai, alpine plants, and moss and succulents! They are easy to use because of their excellent breathability and water retention, and their natural stone texture blends well with plants. Each piece is unique in appearance and size! Due to the natural materials, there may be color unevenness, scratches, and stains. The box has the same capacity, but the number of stones that fit will vary depending on the size.
