Thank you for viewing. Authentic antique K18 rimless round glasses. Lenses are damaged. I don't know the weight because the lenses are present. Authenticity has been confirmed by an optician. I was told that it may be from the 1900s or earlier. When negotiating the price, please provide a specific price offer. *Please refrain from purchasing if you are nervous about home storage. *There may be small stains and scratches due to aging. *The outer box may have discoloration, stains, and tears. *Please judge the condition from the photos and purchase only if you are satisfied. *All accessories are shown in the photos.
