These are marbles I used to play with when I was an elementary school student. I took good care of them, so I think they're still in good condition. I'm a little worried that the photos won't fully convey their beauty, but they have a rare, metallic yellow color and are very beautiful. I think they would be useful as decorations as well. *Please understand that if the actual appearance differs slightly from the photos, it is due to the limitations of the photos.
