These blocks are a great value. My son has a bunch of action figures, sensory toys, plush toys, etc. but what he plays with most is these. We found a deal on some a while back and he kept asking for more so we bought these off Amazon and now he can sit for hours building robots and monsters from his imagination out of these blocks, make up whole back stories about them, then break them down and put together new things. He even uses his Sonic the hedgehog figures with these like saying his robots are creations of Dr. Robonik that attack his Sonic figures. They’re very bright and sturdy and have all sorts of ways to combine them. They have super inviting colors and the possibilities are almost endless. They fit nice and snug together and stay put but are easy take apart. They come with stackable boxes that close tight and hold them for easy storage. They seem expensive but the amount of time kids spend creating their visions out of them totally makes it worth it.
