I made glass nuggets by firing glass. The back is flat. You can glue the parts as they are and use them for earrings, encapsulate them in resin, or use them as materials for handmade crafts. Please check the size in the image (ᴗ͈ˬᴗ͈) These are handmade by an amateur. There may be white mold release agent remaining on the back, and there may be roughness. Some may have burrs. The size, shape, and pattern also vary. Please refrain from purchasing if you are looking for perfect items. I take care to photograph the images to be as close to the actual product as possible, but the appearance may differ from the actual product depending on the environment. Please understand. Since they are glass, they may break with a strong impact. They will be placed in a vinyl pack, wrapped in bubble wrap, and shipped in an envelope via non-standard mail. As a combined discount, we will offer -100 yen for 2 items and -200 yen for 3 items. Please let me know in the comments, and I will create a dedicated listing for you. We cannot offer discounts after purchase, so please be aware of this. (The first person to purchase will have priority.)
