BJ Classic Collection S-801 model, prescription glasses with a black frame. - Brand: BJ Classic Collection - Model: S-801 - Frame color: Black - Lens type: Prescription Thank you for looking. There are no demo lenses. I purchased these several years ago, but I haven't used them much, so they are in pretty good condition. However, they have been stored at home and are used. I appreciate your understanding. I will also include an unused case.
