Used by a child for about half a year. Purchased about 5 years ago. It works well with strings developed by Pirastro, and is made to bring out the best tone when used with those strings and rosin. This PIranito is especially compatible with fractional instruments and is a popular rosin for beginners. It's an affordable product made in a compact size, making it easy to apply even for those using rosin for the first time. Manufacturer's suggested retail price: ¥1,650
