Material: Glass This is a super rare type of sea glass. If you look closely, it's shaped like Mt. Fuji (in my opinion). The color is a pale white. Most sea glass is flat, but this is miraculously 3D. The edges are also relatively smooth. The 1-yen coin is for size comparison and will not be included.

I'm not good at negotiating prices, so please understand.
