Review: Expensive and you need lots of them but worth it - Really expensive, and you should really spring for the large set. We have this set plus a large set in the car. It was really expensive, but this toy is played with daily and we bought it when our kid was six. Our six-year-old plays with a daily and when we have kids over, they all love playing with it. We bought it after playing with it at a friend’s house after the mother told me that this toy had survived dozens of toy purges throughout the years as it was so consistently played with. It’s expensive, but it seems to stand the test of time in terms of interest from kids. It’s also lightweight so they can move a giant box of these around ( they are probably moving $200 worth of blocks at that point but 🫠
Review: Great toy - teeth marks visible if bit - This is a wonderful, open ended, toy. The magnetic strength is both strong enough to feel sturdy and easy enough for my 16 month old to take the blocks apart. My only warning is that there will be teeth marks if your kid decides to bite down on the blocks. The material is foam so the teeth marks do not disappear.

### ⭐⭐⭐⭐⭐ Incredible!

This is the most used toy in our home by my very active and non-toy playing 4 year old. I wish they’d come out with more shapes because I’d buy them all. Endless creativity.
