Unfortunately it wasn’t in a package, so arrived with a large postage label stuck on the front, which won’t come off. The box was also damaged. Disappointed. ### ⭐⭐⭐⭐⭐ Excellent toy great for all ages. *by on Reviewed in Canada 18 April 2024* I bought this for my grandson's and it is a great success I bought 3 sets put them onto my wall turned out the adults love it just as much. The stickies could be stickier but I used tape to help. Thanks very happy. ### ⭐⭐⭐⭐ Doesn't stick to wall *by on Reviewed in the United States 10 July 2026* I bought this for my grandson who just turned 6. He loves it. I gave it 5 stars because it keeps falling off the wall. It doesn't stick well at all. ## Frequently Bought Together - Gecko Run Marble Run Loop Expansion Pack by Thames & Kosmos – Extra Stunt for Vertical Marble Run Starter Set; Fast, No-Mess Setup with Residue-Free Nano-Adhesive Pads for Hours of Creative Play - Gecko Run Marble Run Deluxe Starter Set by Thames & Kosmos – Vertical Marble Run w/Flexible Tracks, Loop & Trampoline Tricks, Fast, No-Mess Setup, Residue-Free Nano-Adhesive Pads for Creative Play - Gecko Run, Starter Set - Experimentierkasten --- ## 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.no/products/610076554-thames-and-kosmos-gecko-run-marble-run-loop-expansion-pack](https://www.desertcart.no/products/610076554-thames-and-kosmos-gecko-run-marble-run-loop-expansion-pack) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
