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 ### ⭐⭐⭐⭐⭐ Circuit de billes original *by on Reviewed in France 26 December 2024* Cadeau de noël pour mon fils.
