*Regardless of whether the service is complimentary or paid, rings sent for resizing or exchange will be shipped back to you approximately 7 to 9 weeks after we receive them. However, the delivery time may be longer depending on the design and condition of the ring, or due to national holidays. Please note that the aforementioned resizing period of 7 to 9 weeks does not include the initial inquiry period or the shipping period to Japan.

If you are unsure about which ring size you require, you can order a Ring Sizing Kit to measure your Japanese ring size.
