The Letter Final Pe has a size of 3X5 kulmusim and is similar to the Pay Kefufa, as they both have an upside down Vov at the top left end, whose head (of the Vov) enters the face of the Pe. Where they differ is in the right leg, whereas the Pay Kefufa has a curled body, the right leg of the Final Pe goes straight down. Of course, the head of the Vov should not touch the right leg, and the right leg should be clearly longer than the upside down Vov, since it otherwise can be invalid.
