Will it hold up?** A: I tried with a kids parachute and it fell down! I made a house last night and it had fallen down by this morning, the straws aren't very strong but it is a really good toy for kids, we've just made a boat! You can get den making kits with sturdy sticks and connectors which would be better for dens but I would get this too as the bendy sticks allow you to make lots of different shapes. You get lots of pieces in the box. ## Frequently Bought Together - SIENIANLINE Straw Constructor STEM Building Toys 480 pcs Interlocking Plastic Educational Toys Engineering Building Blocks -Fun- Educational- Safe for Kids- Develops Motor Skills-Construction Blocks - SIENIANLINE Gears Interlocking Learning Set, STEM Construction Toy Set - Building Kit Toys 180 Pcs - 10 Colors - burgkidz 188 Piece Pipe Tube Toy, Sensory Water Tube Locks Construction Building Blocks, Educational Building Learning Toys with Wheels and Baseplate for Kids Boys Girls Age 3+ --- ## 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.hu/products/699250107-sienianline-straw-constructor-stem-building-toys-480-pcs-interlocking-plastic](https://www.desertcart.hu/products/699250107-sienianline-straw-constructor-stem-building-toys-480-pcs-interlocking-plastic) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-04-22*
