These are dome-shaped glass marbles. Suitable for interior decoration, crafts, and as "ohajiki" (traditional Japanese marbles). They can also be used as an accent when placed in transparent vases or flower containers. They are not completely transparent, but they reflect a faint, beautiful color depending on how the light hits them. The image of the marbles in a wine glass is an example of how they look in a transparent container; the wine glass is not included in the product. Only the glass marbles will be shipped.
