I bought these because they were so cute, without even thinking about how I'd use them. I'm afraid they'll just be a waste if I leave them as they are, so I've decided to list them. They're not just simple color patterns; some have intricate designs, like Venetian glass. The previous seller's description said: "These are parts made once with a burner, and small pieces were re-fired in an electric furnace." Each one is handmade with a unique expression. These kinds of parts, which don't have holes like beads, are called "glass nuggets" instead of cabochons. They can be used for stained glass or as accessory parts. I searched "glass nuggets" on Mercari to see, and it became clear how delicate and elaborate these pieces are. There are individual differences in size, but they are approximately: Diameter: Approximately 7mm Thickness: Approximately 4mm Just arranging them on a small glass dish makes them sparkle beautifully.
