I love physical problem puzzles. Many of the puzzles you find in stores are rehashed classics. But these look fresh.

Instead of playing videogames to waste dead time, these puzzles work out your brain.

I like puzzles. Especially difficult ones, they are fun, exasperating, frustrating, and exhilarating when you finally solve it. These have several levels of difficulty so you could get one for your puzzle loving neighbor and a different one for your little niece. Precision cast in metal based on mechanical puzzles from around the world. From Japan. No solutions! If you can't solve it, it will still be nice to look at. Struggle on puzzle solvers!
