When I posted about a wooden keyboard, reader Glaurung rightly complained that "If I am going to pay over $150 for a keyboard, I see absolutely no sane reason why it should use crappy laptop switches instead of durable mechanical switches". I am happy to report that you may now pay $150 for wooden keycaps that attach to durable mechanical switches!
The caps are offered in rosewood, beech and walnut and in in 61, 87 and 108-key sets. Naturally, you can also buy corresponding wooden cases for popular bezel-less keebs like the Anne Pro or get it all pre-assembled.
