Brand: JAPONISM Lenses: Non-prescription gray lenses (25%) Size: 52□16 Made in: Sabae I purchased these but have never used them. I replaced the lenses for this listing, so you can use them with confidence. *No original case included. I will send them in a substitute case. These glasses would also suit those who like KANEKO OPTICAL, 999.9 (Four Nines), and Masunaga Optical. These are glasses that will be useful for both work and leisure. Thank you.
