Thank you for viewing! How about for your handmade projects? These are glass cabochons that change color with temperature. They have a special black coating on the bottom of the clear glass. The colors are black~purple~blue~pink~orange~yellow, or something like that? The order might be different (*’ω’*) I took pictures with adjustments to show the various colors, so there is no variation in the color change between individual pieces. Other colors and sizes are also available. This is the smallest size in the oval shape. This color is the only one available. There may be fine air bubbles, scratches, and inclusions. This product is a special price, so it is not sold individually. If you wish to purchase additional items, you can get a discount of ¥50 off from the second item. Please comment. 【Size】 Approximately 10~10.5 x 8~8.5mm, thickness approximately 6~6.5mm, flat on one side, oval shape, price for 10 pieces. Please refrain from purchasing if you are sensitive to this, as these items are stored at home. Made overseas. There may be fine scratches, chips, dents, distortions, and inclusions. The colors may also differ from the actual product depending on your device. Due to the special price, they will be shipped in a mini-letter envelope, etc. There is no guarantee in case of non-arrival. Air packing is free, but if you wish to have it, the shipping cost will change, so it will be an additional ¥60.
