This was purchased at a power stone shop. It's beautiful, and I bought it, but I never used it and it's been stored away. I think it cost around 1800 yen when I bought it. I think I bought it for allergy対策 (allergy measures), but I don't remember, so please be aware of that! It hasn't been used, but it's a used item, so I'll give it to someone who doesn't mind. m(_ _)m The size is about 1.5cm to 2cm. 50 yen off for combined purchase of accessories ⭐︎
