Cool tool

Why did you pick this product vs others?:There are so many different ways to apply masking fluid. I like to paint in watercolor and I already had a bottle of fluid and using brushes is awkward, so I thought I would give this a try. There’s a little bit of a learning curve but it’s a neat tool. There is a little screw on the side where you can adjust the space that holds the fluid. Having fun with it so far and I don’t need to worry about it clogging.

Using with liquid latex

I ruined a paint brush applying masking fluid for watercolor painting. Therefore, this was suggested. I do struggle a little knowing exactly how much to "fill" the pen, but I do enjoy being able to adjust the size of the lines or dots.

Lost the screw nutfirst time I used it

I only got to use this one time and it worked great! Had not used anything like this for 55 years since I was in drafting class in high school. However, I only used it for masking fluid one time and when I was cleaning it, the little gold screw nut came off. I threaded it back on and put the pen back in the package it came in. When I went to use it the next day, the little gold nut was gone. I've searched for it and looked for a substitute in my vast collection of nuts and bolts and screws, etc. No luck.

I use it for watercolor.

It does the job for me, but isn’t the best quality. I wish it made a really , really thin line, but the price was right.

Great pen for masking fluid!

Thank you, this is amazing…I am new to watercolor painting and just learning about masking fluid. This pen is great when applying the masking fluid. It flows the fluid nicely on the paper. Great product!
