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 a marker, scratches, or tape attached. Approximately 150 grams, 3.5 mm thick. Please use for making small items. 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 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. For combined shipping, the limit is 3 sheets (or 4 sheets if they are small) per package. We will offer a discount on the second item onwards per package. We have set the shipping time to 4-6 days, but we will ship as soon as we are ready. 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.
