Looneng Cross-Hinged Art Ruling Pen for Masking Fluid Fine Lines

Super. I am using regularly. It is very much useful.

This ruling pen works like a charm! I have been using it with pebeo drawing gum (see pic). Fine lines and dots masked are fantastic. See pic of leaves and star dots/comets. It’s easy to spread for larger areas, too. When dry, it just peels off cleanly from the metal tip. I recommend the combo of this ruling pen with blue pebeo drawing gum (masking fluid) for watercolor. I have a white masking fluid pen (generic brand) that pushes out a lot air, resulting in bubbles that ruin fine lines. I gave up on the use of masking fluid for about 2 years, but this combo is going to be such fun! Be aware - The barrel is very slim. (See pic). If you have any issues with finger/grip strength or arthritis in your hands, this particular ruling pen may not work for you.

What I love: 1. It goes on smoothly 2. It adjusts between very fine lines for hair to thicker lines. 3. It cleans up completely and saves fine brushes. 4. The reservoir makes it possible to draw several fine lines before needing to dip again. This makes it quick so you can put the cap on in less time, therefore preventing the resist drying out. 5. I have only used this with Pebeo resist. I can't say it works as well using other products, because I haven't tied it with any other brands of resist. I am one happy girl! This reduced tons of frustration!

Great tool for precise masking in my watercolours

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.

Works great with ink but I use it first masking fluid in my watercolor art.
