Inkbrush

The Inkbrush is a unreleased Roller-type weapon. It comes in a set with the Sprinkler and the Inkstrike. 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 will be released in a post-release update in the game.
