Finally someone had the same watercolor dream us at Starvin' Artist. Masquepen minimizes work and eliminates mess by combining masking fluid and brush – simplifying the process of protecting areas of a painting from paint. This watercolor supply is revolutionary. Well not quite that, but it's clean and cool. The Masquepen masking fluid comes off easily even after days on a surface – the dried liquid is translucent allowing one to see beneath the area of coverage. The Masquepen comes with an applicator and 1 oz. of liquid masking fluid. Supernib fits over the regular nib and allows you to make spider web thin lines – it is packaged with a cleaning bottle.
