Abstract: An adjustable writing device is provided. The adjustable writing device has a digit engaging member that has an adjustable diameter for functionally engaging a portion of a user's digit without substantially impeding articulation of the digit. The writing device has a cartridge engaging member that includes a writing tip coupled to the cartridge engaging member and an ink cartridge adapted to communicate with the cartridge engaging member to allow ink within the ink cartridge to be dispensed from the writing tip. The writing tip can be oriented substantially orthogonal to an axis of the digit engaging member. A friction fit between the digit engaging member and the digit prevents the writing tip from rotating about the digit.
