Grimm's Semi Circles

Flat where a rainbow curves, the GRIMM’S Semi Circles slot alongside your existing rainbow to open up a whole new dimension of building. Stack them into multi-room towers, line them up as a colourful floor installation, or mix them freely into any construction play.

What’s in the Set

• 11 birch ply pieces in graduated rainbow colours
• Largest piece: 37cm wide × 18cm deep
• Smallest piece: 10cm wide × 5cm deep
• Made in Europe

Endless Combinations

Pair with a GRIMM’S Rainbow to build towers with distinct rooms and archways, or spread them across the floor to create bold, colourful patterns and artworks. Their flat profile makes them easy to combine with blocks, boards, and other loose parts too.

Handcrafted with Care

Each piece is hand-finished from birch ply using non-toxic water-based dyes — no varnish, no lacquer. Natural woodgrain, knots, and markings show through the colour, and every set is subtly unique as a result. Minor colour transfer during play is completely normal with an unvarnished finish.
