Thank you for viewing. ⚠️ Please read this carefully. This glass is broken, so I am offering it at a low price. I bought this before, but I couldn't use the foreign glass, so I put it away. This is a set of two pieces of dichroic glass scraps (black). When I bought it, "104" was written on the back. Expansion coefficient? I'm sorry, I don't know the details. I bought this as is and put it away, but there are scratches. Please refrain from purchasing if you are concerned. Please be aware that the glass may break when you purchase it. It is still cut, so please handle it with care to avoid injury. The size is approximately 20 cm long and 10 cm wide. The thickness is 1.5 mm? It's thin. Please understand that there may be some errors as it is a rough measurement. Shipping and handling fees will be charged, so I cannot offer a discount. Thank you for your understanding. If you have any questions or don't understand anything, please feel free to ask. 4999 yen #glass #dichroic #handmade
