Abstract: An airbrush with a fluid cup or the like which is removably retained on the airbrush and is adapted for containing and delivering fluids to be sprayed by the airbrush. The cup has a hollow reservoir portion and an attached tube portion. The reservoir portion is formed for retaining fluids disposed therein. The tube portion is non-concentrically fixedly attached at one end to a bottom of the reservoir portion and the end distal the reservoir removably inserts into a bore formed in the airbrush. The airbrush has a major axis running the length of the body and the bore in the airbrush is generally formed non-perpendicular to this major axis. The non-concentric mounting of the tube to the reservoir and the angle of the mounting bore permit the removable cup to be rotated within the mounting bore to remove it from the line of sight of a user.

Abstract: An air eraser is provided generally in the nature of a slightly enlarged pen. Compressed air carries particulate abrasive material from the pen for abrasive removal or erasure of indicia or the like on a base. A trigger controlled air valve is provided upstream of the abrasive material whereby it is impossible for any abrasive material to clog the valve. The flow stream through the air eraser is a straight-through one so that there is no problem of abrasive errosion of corners within the eraser.
