Inkbrush

The Inkbrush is a Roller-like weapon that was released as free DLC on June 5th, 2015.

Description
It is similar in ability to the Splat Roller, but covers a smaller area at a much higher speed. Much like the Ink Roller, the Inkbrush can be used as a sort of melee weapon that splatters some ink in front of the Inkling. It comes in a set with the Sprinkler and the Inkstrike.
