Marble Genius Tubes - Marble Run Accessory Add-On Set (30 Pieces), STEM Building & Learning Educational Construction for Ages 4 and Above, Marble Maze Game, With Instruction App Access, Original

I received another vendor's marble set with chutes and the risers. This product works seamlessly with the product I already had. We have 5 grandchildren ranging from 5 years old to under 1. The 4 older grandchildren LOVE when I build a structure. The oldest is now doing more of the building. I not only purchased this set, but also purchased another set that had more base items (to build the structure upon). I can't wait to build again with all these new pieces, which will allow the overall structure to be shorter--which is perfect for the age of my grands! The plastic is sturdy and the pieces fit tightly with what I already had. I suspect I'll be buying more items from this company as our structures grow!!!!

Las piezas están perfectas para hacer crecer este juego divertido.
