We have tons of similar puzzles at home, and it turned out that most of the puzzles here were new to us. They are pretty good quality, the metal is thick, thicker than our old ones, and larger a bit, so they are easier to manipulate. They included solution sheet for the metal puzzles. Some of the days contained plastic puzzles, those weren't as good, but still fun. No solutions for those, but then they are pretty obvious.
