A writing instrument with a cap that lockingly engages a body portion via a locking assembly is presented herein. The locking assembly includes a pair of locking tabs on the cap that correspondingly fit within locking channels on the body of the writing instrument. With the tabs positioned within the locking channels, the cap is twisted or rotated such that the locking tabs slide past a node within the channels and restricts removal of the cap from the body portion.

The end cap of the marker has a large felt or sponge tip to easily erase using a standard whiteboard. A storage cap protects the pens from drying out when being stored.

A multicolor marker assembly for making a multicolored mark on a bingo card includes a bottle that has a plurality of chambers being integrated therein. Each of the chambers contains a fluid pigment of a respective color. An applicator is removably coupled to the bottle and the applicator is comprised of a fluid permeable material to absorb the fluid pigment contained in each of the chambers. Additionally, the applicator releases the fluid pigment in each of the chambers when the applicator is pressed against a surface to make a mark comprising a plurality of colors. A cap is positionable over the applicator to inhibit the applicator from releasing the fluid pigments.
