This is sheet glass for stained glass. I don't know the details. 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. I don't want to receive a bad rating if the size is different after purchase. Please note that there may be markings from a marker, scratches, or tape attached. Approximately 116 grams, thickness 3.5-4 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 will be via Click Post. I 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. There is no guarantee for breakage, so 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 recycled materials such as newspapers and cardboard will be used for packaging. We will pack the items upon completion of payment, 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 per package. Shipping is set for 4-6 days, but we will ship as soon as it's ready. If the weight is within 1 kg including packaging, we will use Click Post, and if it's within 2 kg, we will use Yu-Packet Post.
