I bought these for my kids for Christmas a few years ago after seeing them online and hearing about them from several friends, and they have absolutely lived up to the hype! They’re pricey (mine were about $120 for a set of 100) but the durability and quality is so worth the cost. I have a set of cheaper, off-brand tiles and they’re just not the same. All of my kids love these, and they’ve created endless hours of open-ended play in our home. My 7 and 8 year olds love figuring out ways to build tall buildings that won’t collapse, while my 5 year old loves building houses for her shopkins, and my 3 year old loves that he can make little pyramids with the triangles. Toys that span so many ages like this one are a huge winner in my book!
