    I get asked about these glasses all the time. People can’t believe they’re made from natural horn and finished by hand.

    I’ve owned a lot of frames over the years, but this one stands out. The quality is obvious the moment you put it on. Definitely worth the investment.

    This was my first handmade frame and it feels completely different from plastic or acetate. Warm, smooth, and very natural on the face.
