Magformers Shapes and More 20-Piece Set – Magformers

Twenty pieces is exactly the right number to start with — enough to build something that stands up, few enough that a child can see the whole set at once. Magformers' geometric tiles click together along their edges, and because the magnets rotate inside the frames, they attach every time regardless of which way a piece is turned. No flipping, no rejection, no frustration.

The set arrives in a storage tin that doubles as a magnetic play board, so the building surface and the tidy-up solution are the same object. The magnets are sonic-welded and fully encapsulated within the plastic frames, and the set is fully compliant with US toy safety standards. Flat shapes fold up into three-dimensional structures, which is where the real learning sits — children work out how a square becomes a cube by doing it, not by being told.

Magformers has been making magnetic construction sets since 2005 and remains the reference point for open-frame magnetic building.

Q: How many pieces are in the set?
Twenty geometric tiles.

Q: What makes the tin useful?
It's a storage tin that also works as a magnetic play board, so pieces can be built onto it directly and packed into it afterwards.

Q: Are the magnets secure?
Yes — they're sonic-welded and fully encapsulated inside the plastic frames, and the set meets US toy safety compliance standards.

Q: Will these work with magnetic tiles we already own?
Magformers uses an open-frame design with edge magnets rather than flat solid tiles, so they build differently. Many families use both together, but check the fit with your existing set.

Q: What does it teach?
Spatial reasoning above all — turning flat shapes into 3D structures builds an intuitive grasp of geometry, alongside shape recognition and problem-solving.
