Pearl Pearl PSC-MTB Mallet Bag This popular mallet bag is lightweight and convenient, designed for carrying keyboard mallets and can also be attached to marimbas and xylophones. It can hold approximately 32 mallets and has a removable inner pocket. I purchased this about six months ago and took it outside once, and it has been stored away since then. It is in relatively good condition, but please understand that this is a used item.
