Big Build Bundles

128-Piece Block Party Building Set

Throw a block party in the cube village with 128 magnetic cubes and a mix of bright colors. There are enough pieces for a long picnic table, a stage and a few neighbors' houses lining the street. Kids learn symmetry and structure as they build, and the set works just as well for one focused child as for a crowd of friends.

• 128 magnetic cubes in a bright color mix for long, festive street scenes.
• Introduces symmetry, geometry and structural balance through hands-on building.
• Works equally well for solo concentration or lively group building with friends.
• Durable non-toxic ABS cubes with gentle rounded edges for children ages 3 to 8.
