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 evaluation due to a different size after purchase. Please note that there may be magic marker writing, scratches, and tape attached. Approximately 147 grams, thickness 3.5 mm. Please use it for making small items. 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 it 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 any guarantee for breakage. If you wish to have it shipped as fragile, we will change to Takkyubin (home delivery service) with added 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. For combined shipping, the limit is 3 sheets (or 4 sheets if they are small) 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 it is ready. If the total weight including packaging is within 1 kg, we will ship via Click Post; if it is within 2 kg, we will ship via Yu-Packet Post.
