It is located on the bottom left-hand side of the additional photo column. **Q: Can you connect this magnetic run with the makeway marble run?** A: I do not have the Makeway, but have several other systems. This marble run uses the fridge or metal surface it is attached to in order to hold the marble - as opposed to systems like Fridgits that completely support the marble away from the surface it’s attached to. It might be possible to create a transition from a system like this to another, but it would be difficult to have this system second. The marble would likely fall away as it only supports the marble from underneath on the outside, but supports the marble from the side on the fridge side. **Q: Can you buy more sets to enlarge the experience?** A: I don't know if they sell individual sets of extra pieces, but you could buy 2 or more of this set and I'm sure it would be even more fun. **Q: Will this cause scratches on the fridge?** A: No it won't cause scratches ## Customer Reviews ### ⭐⭐⭐⭐ 面白いです！ *by N***N on February 21, 2026* 磁石が少し弱い感じがしました。 商品は良かったと思います。 ### ⭐ 金属の板に貼り付けるタイプです。 *by I***・ on September 20, 2025* 自立しません。 冷蔵庫程度のおおきさの「磁石がくっつく」金属板が必要です。 ## Frequently Bought Together - NATIONAL GEOGRAPHIC Magnetic Marble Run - 75-Piece STEM Building Set for Kids & Adults with Magnetic Track & Trick Pieces & Marbles for Building A Marble Maze, STEM Project (Amazon Exclusive) - ThinkFun Gravity Maze - Klutz Lego Gear Bots Science/STEM Activity Kit for 8-12 years --- ## 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.sc/products/733521190-national-geographic-magnetic-marble-run-75-piece-stem-building-set](https://www.desertcart.sc/products/733521190-national-geographic-magnetic-marble-run-75-piece-stem-building-set) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-04-23*
