Arcuate arms extending up from the upper end of the body are arranged for being positioned on the sides of the index finger. A concave front groove is arranged along the front side of the body for cradling the tip of the index finger. Concave side grooves are arranged along the sides of the body for cradling the tips of the thumb and middle finger. Forwardly protruding ears are arranged between the front and respective sides for being pinched between the index finger and the thumb, and between the index finger and the middle finger.
