The Frog Guiro/Tone Block makes a fun "ribbit" sound kids will love. The sound is created by scratching the wooden beater on the frog's back. To use as a Tone Block simply strike the resonating body. The handmade 7.5cm (3") Frog Guiro/Tone Block is a real crowd pleaser! Please note wood colour and grain may vary. Recommended for musicians ages three and up.
