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 cannot accept negative feedback due to a difference in size after purchase.

Items 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, making them more prone to breakage. We do not offer compensation for breakage. If you prefer fragile handling, we will change to Takkyubin (home delivery service) with added shipping costs, so please contact us before purchasing. Please note that we use recycled materials such as newspapers and cardboard for packaging. We will pack the items upon payment completion, so we cannot accept requests for combined shipping or changes afterward. For combined shipping, the limit is 3 sheets (or 4 sheets for smaller sizes) per package. Discounts will be applied from the second sheet per package. We have set the shipping time to 4-6 days, but we will ship as soon as preparations are complete. 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.
