Masquepen minimizes work and eliminates mess by combining masking fluid and brush – simplifying the process of protecting areas of a painting from paint. 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 Supernib fits over the regular nib and allows you to make spider web thin lines – it is packaged with a cleaning bottle. Masquepen sets include the Masquepen, Supernib and a cleaning bottle. Refill bottles of maskpen masking fluid are also available separately.
