So worth the buy! - We love these "blocks!" I call them wheels because I don't want my son getting confused and they are shaped like wheels and you can spin them. I like that they come in a plastic storage container with a handle on the lid as well as on the sides where the covers snap shut. It feels pretty durable and much better than the fabric bags that come with a lot of toys these days. The first thing I noticed about these is that they are so bright and colorful, just looking at them is aesthetically pleasing. They do require some fine motor skill which can be a challenge if a child is too young or delayed and therefore potentially frustrating as they do require some force to snap together and take apart, however, if the child is old enough and capable, I definitely think it would be great for developing that skill. These are a fun and novel way that a child can use their imagination to create different shapes and figures. If they are not there yet, they can also just get some sensory input from playing with these, seeing the bright colors, trying to spin them, watching them spin. You can have them sort and match colors as well. It does require some effort to make circles which can be a little tricky so I was blown away when my son made a stack of circles imitating the picture on the booklet and needed help with one and it took me a minute to figure out how he did the others. :) I absolutely recommend these and the price is very reasonable, which I really appreciate as things these days are so expensive and overpriced.

SUCH A FUN TOY!!!! We now have about 600 ot 800 pieces in our bucket! (the pieces are smaller than the image, however) ### ⭐⭐⭐⭐⭐ Multi purpose, excellent purchase, highly recommend! *by B***R on February 27, 2024* This product has several uses and should be a favorite of your child for several years. Other manipulative toys have been a big hit so I purchased two sets of these for my grandson. They are smaller and will develop more fine tuned skills as he masters fitting together and building. There are 8 colors, 25 of each. He is using them for counting, sorting, matching, making different sets. So much to do that he has not become frustrated or lost interest while attempting to fit together. He says that he will try again later and continues to play with them. They are nicely packaged in a snap container with handle. One word of warning-I purchased two sets, as they were well made and reasonably priced. His 34 year old mother kept a set for her use! They are pretty and work her fingers for piano. I am ordering more as gifts, and one for me! I have MS and these are a great physical/occupational therapy tool for my hands. ## Frequently Bought Together - TOMYOU 400 Pieces Building Blocks Kids STEM Toys Educational Building Toys Discs Sets Interlocking Solid Plastic for Preschool Kids Boys and Girls Aged 3+, Safe Material Creativity - Brain Flakes 500 Piece Set, Ages 3+, Interlocking Plastic Disc Toy for Creative Building, Educational STEM Learning, Construction Block Play for Kids, Teens, Adults, Boys, and Girls - Learning Resources STEM Explorers Pixel Art Challenge - Math Puzzles, Pattern Blocks, Creativity for Kids Sensory Bin, Arts and Crafts, Math Manipulatives, Building Toys, Montessori --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/439683711-tomyou-400-pieces-building-blocks-kids-stem-toys-educational-classroom](https://www.desertcart.us/products/439683711-tomyou-400-pieces-building-blocks-kids-stem-toys-educational-classroom) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
