The Letter Mem Stumah(Shlos Mem) comes at the end of a word that ends with a Mem. The Mem Stumah has a size of 3X3 kulmusim. The top right corner should be rounded, while the remaining corners must be squared. The box of space inside the Mem Stumah should also be completely squared, as we want to make the Mem Stumah clearly different from a Samech. There should be a slight potrusion from the top left corner which should extend a little bit past the body of the Mem Stumah. There should not be any splits along any portion of the Mem Stumah, as this would render it invalid.
