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) and add 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 completion of payment, 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. 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 weight is within 1 kg including packaging materials, we will ship via Click Post; if it is within 2 kg, we will ship via Yu-packet Post.
