Annexfun Magnetic Blocks - 100-Piece STEM Building Set for 3+

Experience the Annexfun Magnetic Blocks 100-piece set, a versatile building system designed to spark curiosity in kids 3 years and older. The blue kingdom castle theme invites little architects to imagine towering fortresses, shimmering walls, and winding ramparts as magnets click satisfyingly into place.

Crafted to invite tactile exploration, these blocks pair bright, saturated colors with a textured, satisfying magnetic feel. The pieces connect quickly, so little builders can see an idea take shape in moments, then revise it into something even more ambitious. The result is a hands-on experience that blends play with early spatial reasoning and planning.

Quality you can feel

The blocks are made from food-grade ABS plastic with smooth edges to fit safely in small hands. The magnets are embedded to minimize protrusions, helping kids stack, twist, and reassemble with confidence while keeping the focus on creative play rather than safety concerns.
