I LOOOVE these little magnetic building blocks. My two daughters are obsessed with these magnetic builders. I'm going to need to buy more because they fight over them.
These are square outlines that have magnets in all 4 sides, which is what makes them stick to each other. My kids literally will play with these for 2 hours.
I noticed it helps with my one and a half-year old fine motor skills. The older daughter will build something and my younger daughter will try to imitate what was being built.
It has a little book that comes with it of Direction to build different things. My six-year-old loves looking at the directions and learning to build different things.
After a couple of times playing with the magnetic blocks my older daughter was showing my youngest where to put the block, to build things.
These blocks also have a carrying box which is great so we don't lose any. Such a great toy and it keep the kids of the electronics! I'll be buying another for more play and bigger buildings!
