Unit Rocks introduces a world of building possibilities in one set. A true heirloom toy created to be played together and passed down through generations.

The building is a blast with our 100-piece Unit Rocks set. Castles and forts resemble real structures thanks to our Unit Rocks’ unique design. Perfect to handle, each piece is built to the same size and standard of our traditional bricks, made from solid wood, with hand-carved grooves, and finished in all organic dye. Every Unit Rock is hand finished giving a unique antique feel of stones that have weathered a long history. Truly a gorgeous educational toy. 

With a range of units, half units, pillars, triangles, and arches, our Unit Rocks are a great standalone set to foster STEM-led play and exploration and make an excellent addition to traditional Unit Bricks sets in the larger playroom or class setting. Imaginations leap as buildings take shape with Unit Rocks.
