Thank you for viewing! How about for your handmade projects? This is the price for 4 round pieces. Other sizes are also available. 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 green~yellow~orange~blue~purple~, or something like that? The order might be different (*’ω’*) They have an aurora-like, iridescent appearance. I adjusted the images to show the various colors, so there is no variation in color change between individual pieces. There may be small air bubbles, scratches, and other inclusions. 【Size】 Approximately 16mm in diameter, 9mm thick, flat on one side. Other sizes are also available. These items are on special offer, so they are not sold individually. If you wish to purchase additional items, please comment for a discount of ¥50 off from the second item. Please refrain from purchasing if you are sensitive to items stored at home. These are made overseas. There may be small 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 thick OPP bag via mini-letter or regular mail. There is no guarantee in case of non-arrival. Air packing is free, but if you want it, the shipping cost will change, so it will be an additional ¥60. If you wish to use Mercari shipping or another shipping method with a tracking number, it will be an additional ¥120. Please consult before purchasing. Recycled materials may be used for packaging. Please understand and agree to this before purchasing.
