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 ### ⭐⭐⭐⭐⭐ Un exito *by on Reviewed in Spain 16 February 2025* Lo compre para mi hijo de 10 años y le encanto. Funciona perfecto, nunca lo vi tan enganchado y entretenido con un juguete. La calidad me parecio buena, los imanes agarran bien, quizas hay que hacer algun ajuste despues de haber tirado la bola porque puede que haga pequeños movimientos sobre los imanes y no corre bien la proxima vez, pero es muy divertido ### ⭐⭐⭐⭐⭐ Great toy, a lot of fun! *by on Reviewed in the United States 5 January 2025* I purchased this for my nephews, and it has been a massive hit!

I love how this set encourages creativity and problem-solving while also teaching basic STEM concepts in such a fun and engaging way. My nephews have built everything from simple shapes to complex structures, and their excitement never fades!As a bonus, the included guidebook provides great inspiration for new designs, but the kids love to freestyle their own creations too. It’s a perfect blend of fun and education, and I feel great knowing it’s helping them develop important skills like spatial awareness and teamwork.The quality is fantastic—durable, safe, and well-made. It’s also compact enough to store easily, and the storage bag is a thoughtful addition for keeping everything organized.I would highly recommend this to any parent, teacher, or caregiver looking for a creative, hands-on activity for kids.
