Rainbow Croaking Frog Güiro This brightly coloured carved wooden frog güiro, is made from acacia in northern Thailand. Run the stick provided along the ridges on its back from rear to front to make it croak, or hit it on the head to make a ‘pock’ sound. The method of painting produces a wonderful 'cracked' effect on the instrument which is very aesthetically pleasing. To learn a little bit about the production of our frogs, have a read of our blog. Specifications: 12cm × 8cm × 8cm Origin: Thailand
