I bought these with the intention of putting sand in small glasses and selling them! I'm selling them because I'm planning to move. The sand comes in four colors: light blue, blue, pink, and beige. There are 20g of each color. The glass balls contain small, clear glass and weigh 40g. All items are made in Japan. I also have the glasses, but I can't sell them because the shipping cost would be too high... If anyone wants them, I can ship them for an additional 500 yen (*^^*) This is a wonderful handmade craft using sand. I think even children can make it. Thank you very much (*・ω・)*_ _) *bow* #handmade #colorsand
