We endeavour to ship all items within 3 business days of the order date. If your purchase is urgent (such as a gift), we will do our best to accommodate your request. Please contact us at dearkasei@gmail.com.

Carried via Yamato Transport (Kuroneko TA-Q-BIN), with delivery typically takes 1–3 business days, depending on location.

All items are carefully packaged to protect against damage during transit. KASEI is not responsible for carrier delays, lost parcels, or damage that occurs once the package has left our facility.

Carried via Japan Post EMS, with delivery times varying by region, but typically 3–10 business days from order dispatch. Customers are responsible for customs duties, import taxes, or other fees required by their country.

Fragile or high-value items may be insured at the customer’s discretion. KASEI recommends purchasing insurance for added protection.

All items are packaged using FSC-Certified materials, including double-wall boxes and protective inserts for fragile items. Despite careful packaging, some items may be at risk during shipping due to their vintage and delicate nature.

Tracking information will be provided once your order has shipped. Please note that delivery times are estimates and may vary due to carrier schedules or customs processing.

Due to the unique, one-of-a-kind nature of our items, KASEI maintains a strict final-sale policy. All sales are final. KASEI does not accept returns, exchanges, or refunds after purchase.

KASEI carefully packages all items, but is not responsible for damage or loss once a parcel leaves our facility. Customers are encouraged to purchase shipping insurance for fragile or high-value items.

Ensure that your shipping address is accurate and complete. KASEI cannot be held liable for parcels delivered to an incorrect address provided by the customer.
