Nail Dust Guard - New, Unused Retail Price: ¥16,280 Purchased 4 months ago. Due to insufficient checking, the size didn't fit, and I haven't used it even once since purchasing. There is no yellowing. I will re-wrap it in the original bubble wrap and ship it in a cardboard box. I packed it immediately after taking the photos in the 2nd and 3rd images. There are no scratches or damage during the inspection, but please understand that I cannot be held responsible for any shipping-related issues.
