The magnetic building blocks use magnets embedded inside to remain attached, allowing children to build structures with them.
Based on the interlocking Lego (R) brick, these magnetic building blocks, try to simplify the design by having no external components that can break off. These are meant to excite in the minds of young children the joy of building and creating.
The child can interact with the blocks by putting them together and letting the magnets attract. They can build structures or anything, really, with them. They come in cube (not pictured) and rectangular prism sizes.
As for durability, the blocks are made out of wood, with holes drilled in for the placement of the magnets. The holes are then filled. Not for small children or those with a tendency to eat tiny magnetic objects.
