Mercurry Lezhi IQ Toys-AB A+B Test Mind Game Brain Teaser Wire Magic Trick Toy IQ Puzzle Set (Pack of 16), Metallic

These are amazing for the price! In the past I’ve paid upwards of $5 per puzzle of the same size, so these are just 10/10. They have a great handful and no sharp edges. Some are super easy and others have me spending a decent amount of time taking them apart and putting them together. There ARE instructions on the back of the packaging if you get stuck and need a hint.

I bought lots of "bulk" items to stock my prize box for students. So far, these are the most popular--with varied ages! I teach private music lessons and was surprised that my high schoolers and kindergarteners have all been choosing these! I thought they would mostly appeal to my older students. (Adults don't earn prizes in lessons, but other adults that I've shown them to have also enjoyed figuring them out.) Super great buy. Will definitely purchase again.

This is a nice collection of puzzles at a good price. I use them in my classroom for students who need a little something to mess with. They are not too noisy, being a small size. I would definitely buy them again.

these are wonderful! small and easy to figure out.we got them as table toppers for my parents 50th anniversary... we put a few of these on each of the tables (it kept the kids and adults both entertained!)i keep a couple in my purse.... anytime i am out at restaurant and see a kid fidgiting i hand them one of these.

I like these, but they are flexible enough that people can just force them to "solve" them. They are fun, and I took some with me to a meeting at work for folks to play with before the meeting started. (I figured that it would be good to have people's brains in thinking mode from the beginning.) I've also put them on the coffee table during a party and they were entertaining. I wouldn't buy them again, but instead would buy bigger ones. If these were offered in a larger size as the same groupling, I'd buy that.
