This toddler-sized shaker produces a fun clackety sound when shaken from side to side. It is made entirely of rubberwood, which has a very smooth finish and will not produce any splinters, and it is finished with a non-toxic, water-based clear coat and paint that is safe for mouth contact. The shaker measures 12 cm (about 5") long, and has a well-designed handle for easy gripping. Musical instruments are excellent for the development of physical coordination, motor skills, sensory processing and a sense of rhythm.
