18165 Solo Goya Masking Marker Medium Line Width 2-4 mm Removable Scratch Tape in Marker Shape for Precise and Edge-Sharp Lines in the Middle of Flowing Watercolour Paint

The fine tip makes it easier to create detailed images. A good product.

EASY to use & comes off after painting easily just by using my fingers to rub it off. Other items I've used rip my paper, or tear it. LOVE THIS!!

The tip on this pen isn't as fine as if you were using a detail brush to place masking fluid on paper, but it's pretty darn close if your careful. If I hold the pen straight up and down and don't use much pressure, I can make some tiny marks and create fairly fine lines. I love how easy and mess-free this is to use. I love that I'll have no more accidental blobs of masking fluid on my paper or ruined brushes. When it's first applied the masking fluid looks so light that it's hard to believe it won't rub off when painting or that it'll sufficiently mask the area, but it works great! I'll still pull out my masking fluid bottle if I need to create super fine details or if I need to cover a large area, but for everything else, I'm completely sold on using this pen instead. So much less hassle!

Fine point makes it easier to use on watercolor.Will order again

I was excited by the possibility of masking fine lines...but sadly the light blue color added to the fluid remains on the watercolor paper after the "rubbery" mask has been removed. This makes it worse than useless for masking retained white areas in watercolor paintings.
