Ili'ili Hula Dance 6.5-6.9 cm These are natural stones without polishing or paint. I purchased a large quantity from a hālau several years ago. These are new and unused. I hope someone will take them over. They are about half price. There may be unevenness, distortions, and scratches due to the natural stone, but there is no problem with the sound they produce. Please check the images. They are a comfortable size to hold. Length: Approximately 6.5-6.9 cm Width: Approximately 3.5-4.0 cm Thickness: Approximately 1.8-2.1 cm I manage a lot of them in the classroom, so please contact me if you need a large quantity. #HulaDance #Kahiko #Hawaii #Hawaiian
