ROLF is a small family-run business in the Tyrollean Alps. Everything from frames, hinge construction to sample cases and photos are made by the team. The finish of the frames is incredible and they are very comfortable and wearable even as ophthalmic frames. I tried several of their models at the fair and they fitted me great, without any adjustment needed (which is very important when buying a wood frame though they unfortunately aren’t adjustable).
The frames are totally made of wood, woodstone and some of the models are even available with buffalo temples. The prices are very various depending on the wood. This is a really high-end handcrafting, almost too good to be truth.
