Review: Good puzzle - Good puzzle
Review: Easy, but beautifully made little puzzle - This is the first proper "disassemble and assemble" puzzle I've had (other than the cheap ones that come in crackers). As it's the lowest difficulty rating it comes disassembled, where the harder ones come assembled to be taken apart and assembled again. I completed the 'Diamond' in about 20 seconds, it's an easy one, but the level of satisfaction was still high when it slides together, which makes me want to get more and more of these by Hanayama. The two pieces are made from a nice heavy metal which feels great in the hand and when completed it looks like an ornament, which could sit in any setting, waiting to be picked up and played around with. It may be easy as puzzles go, but it has massive fidget appeal – it's great to absentmindedly play around with, and solving it one-handed is very fun when you get used to the movements. I'm now hooked on these Hanayama puzzles.
