These are a bit larger than an inch, but size didn't really matter to me because it's a different take on building rather than using legos and blocks or tiles. The set came with plenty for building. I did look on youtube to see the various things that can be built with these, and there is a lot. I also purchased the brainflakes wheels and axles set for building vehicles. It's a pretty neat set when purchased together. There is a website to go to where you can print out free or purchased builds like a sword which I seen on youtube as well. If your child or adult is big on building, I believe this is a cool set to add to their collection of building toys. Plus, it encourages different aspects of Steam. Art and engineering for sure off bat, but you can get creative and use these as manipulatives for math or throw a battery on it and make a functioning robot for technology. My nephews, sons, and I are going to have quite a bit of fun with these as we enjoy building toys. I will probably have to purchase more in the future, but its a starter set for Christmas to see if they will enjoy them as much as I believe. I am 10/ 10 satisfied with my purchase they are quite thick as well and visably not cheap plastic. I will do an updated review a few months after Christmas if these are holding up well to my expectations or not.
