We will pack carefully, but there is a possibility of breakage during transportation. Especially when purchasing multiple items, they will be stacked and become more fragile. We do not offer a guarantee for breakage. If you wish to have it shipped as fragile cargo, 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 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 it is 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.
