Straw length: 7.87inch Straw diameter: 0.27inch Star size: 0.9*0.9inch Review: Excellent, creative, stimulating - Great storage case Wonderful fun and creative for the kiddos. Keeps them occupied thinking of fun things to make. Review: Excellent purchase. - This was for my eight-year-old grandson's birthday. Out of all his gifts, this was the first thing he wanted to create something with. I'm not sure why others had problems, it's not built at NASA. The long pieces are slightly bendable which really was a plus with some projects he put together. I would have worried more if they were stiff plastic sticks if they broke and splintered. The bigger the creation, the softer plastic did bend a little due to the overall weight. He made one design using every stick that was big enough to be a wall divider. Obviously, that one did tip over, but it made it more fun seeing how far he could go. It's great for learning balance and leverage and just good hand-eye coordination. He has a six-year-old brother that also plays with it. I don't remember the age range, but with parental help, younger kids can enjoy it too. It's really a good gender-neutral toy...both boys and girls seem to have fun with it. There are enough pieces to divide and let several kids make their own creations. Loved it! I put 4 stars for easy to assemble for children younger than 7-8. And 4 stars for sturdiness for those bigger creations that might be too top heavy etc. ## Features - Includes 800 pieces.

The connector fits snugly into the sturdy straw pieces. They're easy to connect, and stay together until pulled apart. **Q: Happy Holidays. How many straws are there from the 800 pc set?** A: Too many to count. My granddaughter makes things out of this set all the time but they are not sturdy enough to make a fort with a sheet cover. **Q: Are they sturdy enough for rough kids?** A: Yes they are. My kids are rough and none have broken. **Q: Does it come with a storage bin?** A: Ours did not but it did come with a plastic zipper bag that stores them all perfectly and has lasted for years now. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, creative, stimulating *by S***I on May 5, 2025* Great storage case Wonderful fun and creative for the kiddos.

It's great because they can build things that they can fit inside of, crawl through, and even wear (silly helmets, ect). This is a really fun toy. The sticks are basically thick straws. they are relatively easy use, but if they get bent and creased than they will always bend in that spot, just like a plastic drink straw. ## Frequently Bought Together - Straw Constructor STEM Building Toys 800 pcs-Colorful Interlocking Plastic Enginnering Toys- Fun- Educational- Safe for Kids- Develops Motor Skills-Construction Blocks- Best Gift for Boys and Girls - 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, 402 Pieces, Ages 5+, STEM Toys for Kids, Coding Basics for Kids, STEM Activities for Classroom --- ## 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.de/products/78666308-straw-constructor-stem-building-toys-800-pcs-colorful-interlocking-plastic](https://www.desertcart.de/products/78666308-straw-constructor-stem-building-toys-800-pcs-colorful-interlocking-plastic) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-18*
