A pen or pencil is inserted through the Palm Pen Holder pen hole and is fixed in place by tightening a set screw to allow for different writing utensil sizes. The device can be gripped in multiple ways and also gently squeezes the hand for stability when writing. With different sizing available, this device works well with narrow writing utensils like paintbrushes or wider ones like sharpie markers. In addition, the device itself has alternate sizing to provide options for the user.

There are small, medium, and large-sized Palm Pen Holder available for different hand sizes. In addition, the pen hole diameter can also be changed from narrow, standard, and wide. By use of the set screw, the writing utensil does not need to be the exact size of the pen hole but rather the sizing is available to fit large writing devices like markers and narrow ones such as fine paintbrushes.
