The Masking Fluid Pen and SuperNib work like resist pens. Now you can make precise, controlled lines, dots, or area coverage with ease. No need for a brush. Simply apply the masking fluid over the area to be protected and let dry. Once dry, paint over the protected area and let dry again. Now, peel off the dried mask or resist to reveal the uncolored area. There are two sizes of the Masking Fluid Pen: regular and fine (SuperNib). The Masking Fluid Pen dispensing tip is 1/2" and the SuperNib is 1". The unique cap/wire system ensures a continuous flow of liquid from start to finish, always precise and controlled. No cleaning required.MVMP1112 - 1.25 oz.
