Items listed for two weeks will be cut and sold as scrap, 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 transport. Especially when purchasing multiple items, they will be packed together, making them more prone to breakage. We do not offer a guarantee 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 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 afterward. For combined shipping, the limit is 3 sheets (or 4 sheets for smaller sizes) 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 preparations are complete. 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.
