👓 **Lens Information**

This item is for the sale of the glasses frame only.

If the used glasses have lenses installed, the lenses will be removed and only the frame will be shipped if they can be separated.

Due to the nature of vintage glasses, the original lenses may be included as demo lenses for the purpose of making new lenses at an optical shop if it is difficult to make new lenses without them.

Rimless, semi-rimless, and some specially structured glasses may be shipped with lenses installed to maintain shape and for safe storage and delivery, as it is difficult for individuals to detach the lenses or there is a risk of frame damage if separated excessively.

In this case, the lenses are demo lenses (accessories) and not for sale, and cannot be used or worn for vision correction purposes.

You must replace them with new lenses at an optical shop. By purchasing, you are deemed to have agreed to the above notice.
