Rubberwood blocks with five different pitches for fun rhythmic play. When struck with a mallet the blocks sound higher or lower depending on their size – the smaller the block the higher the pitch. 12.5” ergonomically designed Mangowood base fits easily in your lap or on a table. Includes pair of wood mallets. According to Brett Sommers of Figpickels Toy Emporium in Coer D’Alene Idaho, not only do the toys have musical value, but kids are attracted to the bright, candy-like colors. Retail box will hang.
