Thank you for viewing. Everything shown in the photos will be included. This is stained glass material. Manufacturer: Unknown - Colors: Amber, Red, Green - Size: Approximately 30cm x 15cm I believe this is a type of glass with a unique and hard-to-find texture. I purchased it many years ago but am not using it, so I'm offering it to someone who needs it. I will carefully pack the item to prevent breakage, but as it is a glass product, there is still a possibility of cracks or chips occurring during shipping. Due to the nature of the product, we cannot accept returns or exchanges in such cases. Please purchase only if you understand and accept this. I will thoroughly wipe off any dirt and clean it before shipping, but please understand that as it has been stored for a long time, there may be dirt, dust, chips, writing marks, or cut marks. (Please note that there may be oversights due to amateur inspection). In addition, there may be streaks, bubbles, small scratches, and stains that are characteristic of glass products and occur during the manufacturing process (please refrain from purchasing if you are concerned about minor details). Also, please consider that there may be differences in color due to your computer environment or smartphone, and that there may be errors in size and other numerical values. #stainedglass #sheetglass #scrapmaterial #handmade
