It’s so hard to build stuff when they keep coming apart . ### ⭐⭐⭐⭐⭐ Excellent building kit for young kids *by L***A on Reviewed in the United States on January 13, 2020* This was a present for my 3year old grandson. He has several building sets. Whenever I visit this is one of the things we do together. What I like about this set is he does not need help to play with it. The pieces fit together well but not so tightly that he can’t take them apart when he wants.He loves wheels and this has enough. It has enough of everything to not need several kits to build something cool. And the box has locking handles so everything can be put away at the end of the day and not get lost. ### ⭐⭐⭐⭐⭐ Sturdy and creative set! *by H***P on Reviewed in the United States on August 18, 2018* These are great! Each piece can serve multiple functions and are different colors which means almost anything can be made. Perfect for creative, young minds. Our son is 2.5 years so he enjoyed when we got in on the fun with him, “Make a truck!” I can see a 3 or 4 year old being able to build on their own. The pieces are very sturdy so no fears of broken sharp pieces or choking hazards. My only suggestion would be to provide a larger storage box as fitting everything back in is a bit tricky. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/77566185-cossy-engineering-blocks-for-kids-15-shapes-super-fun-colorful](https://www.desertcart.tn/products/77566185-cossy-engineering-blocks-for-kids-15-shapes-super-fun-colorful) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-20*
