Abstract
Apparatuses and methods for providing a multi-media writing instrument having locking grips. The grips are locked into position so that they will not rotate around the outer diameter of the pen. In particular, the upper grip of the multi-media writing instrument contains an indicator which denotes to the user the type of writing element being used and acts to lock the grip in position.
