Stained glass sheet glass. Details are unknown. There are also images with light shining through, so please check the photos. The size can be confirmed with the ruler in the image, so please check it yourself. We do not want to receive a negative review stating that the size was different after purchase. Please note that there may be markings from markers, scratches, and tape. Approximately 99 grams, 3mm thick. Please use for small item production. Items that have been listed for two weeks will be cut and sold as scraps, so please purchase any glass you like as soon as possible. Shipping via Click Post. We will pack carefully, but there is a possibility of breakage during transportation. Especially when purchasing multiple items, they will be stacked for packing, making them more prone to breakage. We do not offer compensation for breakage. If you wish to have it shipped as fragile cargo, we will change to Takkyubin (home delivery service) and add shipping costs, so please contact us before purchasing. Please note that we will use recycled materials such as newspapers and cardboard for packaging. We will pack the item upon payment completion, so we cannot accept requests for combined shipping or changes after that. The limit for combined shipping is 3 sheets (or 4 sheets if they are small) per package. Discounts will be applied from the second sheet onwards per package. We have set the shipping time to 4-6 days, but we will ship as soon as it is ready. If the weight is within 1 kg including packaging materials, we will ship via Click Post; if it is within 2 kg, we will ship via Yu-packet Post.
