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 be aware that there may be markings from a marker, scratches, or tape attached. Approximately 168 grams, 3mm thick. Please use for small item creation. Items listed for two weeks will be cut and sold as scrap materials, 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 packed together, making them more prone to breakage. We do not offer compensation for breakage. If you wish to have it shipped as fragile, 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 items 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 for smaller sizes) per package. Discounts will be applied from the second item onwards 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, we will ship via Click Post; if it is within 2 kg, we will ship via Yu-packet Post.
