This is a sizing kit for the LUNA RING2. For those who want to measure their size immediately or try it on. If you're ordering from overseas, it takes time for the sizing kit to arrive, so how about this? We'll ship it by the next morning. Please note that the sizing kit is originally free, so if you're not in a hurry, we recommend ordering from the official LUNA RING website as usual. If you purchase this along with the ULTRA HUMAN currently on sale, we'll discount the shipping cost, so please request a combined purchase. Regarding the condition of the box, there may be some crushed corners or scratches due to being transported from overseas, but the contents are not affected. This is just a sizing kit, so we plan to send it in simple packaging. We appreciate your understanding. - Brand: LUNA RING - Accessories: Ring size confirmation samples - Features: Includes multiple samples for ring size confirmation #SmartRing #SizingKit #LUNARUNG #LUNAZONE
