With 100 colorful wooden building pieces - cubes, arches, cylinders, and peaked roof shapes in red, blue, green, and yellow - this set turns open floor space into an endless building site. Stack them into towers, arch them into bridges and doorways, or follow the castle design on the box as a starting point before branching off into an entirely original creation of a child's own choosing. With this many pieces on hand, there's always enough for a sibling or friend to join in without anyone running short. Every piece packs away into its own round, sturdy tub with a carrying handle, making cleanup almost as satisfying as the building itself. This set also pairs naturally with other goki building block sets, combining for an even bigger and more varied collection to build with. Finished in bright, water-based colors, it's a generous starter set for hours of open-ended building. For kids ages 2 and up.
