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 transit. Especially when purchasing multiple items, they will be stacked and become more fragile. We do not offer compensation for breakage. If you would like fragile handling, we can change to Takkyubin (home delivery service) with added shipping costs. 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. 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. 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.
