The Markie journal has two hands depicting the left and right hands. Each finger in the journal has a circle with quadrants to mark lancet injections. The standard journal has a circle at the fingertip that is easily customizable if you are mostly concerned about injection sites. For single finger use, color in the space closest to the injection point for easy tracking. If you use multiple injection sites on a finger, color in the quadrant space closest to the injection site for easy tracking.
