The bottom part is a glass float, and water was sealed inside. However, one side was dropped, and the glass part is partially damaged, causing the water to leak out. The damaged part isn't very sharp, but please handle with care as there is a risk of injury. Please handle with care as it is a delicate item. It was originally priced around 4000 yen at a shop that handles handmade items and natural stone accessories, so I believe the parts used are of high quality. I hope you find it useful. Please understand that this is a used item, and those seeking a perfect item should refrain from purchasing.
