This item was purchased about 11 years ago from an authorized Rakuten shop. The original purchase price was ¥41,720. I have multiple pairs of collection glasses, and I never had the opportunity to use these with prescription lenses, so they have been stored at home. At the time, there was no original case, so the unused glasses will be shipped in an aftermarket case. The current retail price is ¥46,000. I hope someone will take them.
