An expansion to the best selling series of marimba mallets, the Robert van Sice signature vibraphone series keyboard mallets are a new voice in the category, offering a beautiful lush sound on instrument without the front end attack characteristic of many vibraphone mallet models. Designed for the solo and chamber percussionists, these mallets blend into the ensemble unlike anything else available, allowing the vibraphone player to feel as comfortable in the concert hall as they do on stage at a club.

The M312 is a medium soft mallet that picks up where the 311 leaves off. The slightly harder core gives the player sound clarity while still blending seamlessly in a chamber music setting.
