Thank you for viewing. This is a Saito Japan M-3. The yarn on the head is slightly frayed, but it's still usable without re-wrapping. It seems to be difficult to obtain this mallet now, making it a rare item. For reference, the price of a new set of 4 is ¥11,000. The hardness is soft, and despite the small head size, it has weight, allowing it to produce a light, clear tone. Please feel free to comment if you have any questions. #Marimba #Vibraphone #Percussion
