Rainbow Prisms™

🌈 Rainbow Prisms™

A Bold Geometric Building Set for Bigger, Brighter Builds

Sixteen large lucite triangles. Sixteen radiant colours. Endless ways to build.

The Rainbow Prisms™ are designed to bring bold geometry, colour, and architectural detail to open-ended play.

At the heart of the set are 16 large right-angle lucite triangles in 16 different colours, paired with 4 large wooden square frames and 8 wooden triangle frames that the lucite pieces can fit into, layer with, and build around.

The result is a set with enormous versatility.

Use the prisms as rooftops, corners, walls, moats, pathways, architectural details, or striking standalone building pieces. Fit them into the wooden frames for a completely different look, or combine them with your existing blocks to add shape, height, and colour to larger constructions.

They are especially beautiful alongside our Kingdom sets, where the larger triangular forms can transform castles, towers, bridges, and small-world scenes with just a few pieces.
