Brand new, unused. These are photochromic sunglasses. Videos and other information are available on the official overseas website, allowing you to see how the photochromic lenses work. Retail price is approximately 35,000 yen. Available for immediate purchase. Will be carefully packaged and shipped. This is a new, unopened product. Currently, the price is not negotiable. Shipping is generally expected within 2-3 days, but due to business trips and other absences, I've set the shipping time to 4-7 days just in case.
