Bishop’s new disposable grips are exclusively compatible with the Bishop SMP Pen Machines. They offer SMP Pen buyers a sterilized, convenient, and more sanitary grip option.  The grips are offered in both Standard & Thin sizes, similar to the grips included with the Pen Machines, which allows artists to customize their comfort.  In addition, they are made with high density foam material, which promotes comfort and reduces the feel of vibration.
