Our Wooden Sound Prims have been redesigned with a wider variety of sound pairings and better sound quality.
The set contains 6 pairs of beautiful hardwood triangular prisms, identifiable by matching percussive or musical sounds and colour coded musical note logos in 6 rainbow colours. The note logo only appears on one end of the block so they can be turned upside-down to test the user's discriminatory skills.
Size: 50mm x 60mm each
