These are collaboration glasses with Sailor Moon Crystal, which was sold about 5 years ago. 

The image is Silver Crystal. 

As the name suggests, the gray frame and one point are Swarovski crystals and the flowering Silver Crystal. 

Originally it was made to order and the price was higher than other sailor guardian models, so it is an item that is not often seen in Japan. 

I have never worn these glasses.

To American buyers 

Japan Post has stopped shipping by Air.  

It can be shipped by Surface, but it takes about 3 months to arrive.  

Please think carefully before purchasing as it may take more than 3 months.

Australia and Canada only accept FedEx shipments.
