MOLOTOWGRAFX Masking Fluid Pump Marker, 2mm, 1 Each (728.001)

I have used lots of masking fluids for tiny areas of my paintings. This stuff comes in a small size and is refillable it’s the first time I’ve experienced a masking fluid that doesn’t dry so fast it clogs up the applicator, and the entire thing gets trashed. Just a couple pushes on a scrap paper and it starts to flow and dot my areas marked out to be masked. It is smooth and doesn’t make big blobs, easy to control the flow

I ordered two of these each a different size. They must have come from two different locations because they arrived on different days. The first one I opened looked suspicious right off the bat. The colors of the liquid were all separated within the pen. I tried shaking it to mix it...Not Mixing At All! I try using it for some unknown reason. This effort was futile as well. I tried squeezing it. The liquid inside the tube was hard as a rock. I tried to open the pen, but the hard liquid inside was unyielding. Pliers didn't help.I get back on my Amazon Account to return the item. Much to my surprise I was informed that this item may NOT BE RETURNED nor will they give refunds. WTF?? So I contact the company, it's located in Switzerland. SMH. I found a good translator and sent in a complaint. I seriously doubt I'll hear back from them.I held out hope knowing that I had another one coming. When it was delivered I opened it immediately. Much to my dismay this pen was in the same condition. Granted the separation was vertical rather than horizontal, but separation and hardness ruled the day.TWO STRIKES, this item is OUT!! Save your money and make a trip to your Hobby Store.

This is a great tool. Wasn’t sure about the pen design but surprisingly works great. Not going to do super fine lines but once you get the hang of it you can achieve pretty fine lines. A thinner amount works better than thick (tested in lines and circles), they say not to leave it on more than 2 days but I’d be nervous for anything longer than 24hrs. I used it on non-watercolor paper... quality sketch paper but I really don’t expect It to work but it did! However where I had circles (thicker amount) it left behind a blue tent so I’d be careful and rest the paper first for sure but even on this paper the thing lines were perfect. tip: use a zip lock bag and rub in a circular fashion to remove it

I use masking fluid, I know how it works. I spent a very long time trying to get it to work and had no luck. It was incredibly frustrating. I even took it apart and tried to get the fluid to move or come out. Nothing. I assume it's dried in there, I don't know. Thankfully it was Amazon and they immediately dealt with my return and refund. Just in case this happens to you, I wanted you to know you are not alone. I'm hoping a new order will actually work. 🤞🏼UPDATE: my new one arrived in good shape, no dried clumps like the last that had not a bit of liquid in there. I just had the most frustrating experience with it, though. I use Windsor and Newton masking fluid and it's great, but this watercolor, I wanted thinner lines and I was so excited to be able to just draw in the fluid. Getting it on was not too difficult. I waited until it was dry, it didn't take too long and did a wash of colors and as soon as that dried, I tried to remove the fluid. I've been sitting here for an hour using erasers, cloths, rubber blocks, and anything I could find. I cannot get the glue off. Not only that, it ripped the paper in one spot. I'm exhausted and frustrated and I'm done with this pen. It has not saved me time, no has it been helpful in my art. Stay far far away. Get Windsor and Newton and use a thin brush. This is trash.

I bought this masking fluid marker for use in my illustration work on the recommendation of another artist. While I wasn't sure what to expect after reading the reviews on here, I decided to give it a go for myself and I'm so glad that I did. I have come to appreciate how easy it is to see this masking fluid on my paper when I am ready to remove it. The blue color does not stain the paper. I also find it easy to apply after a few pumps to get the fluid flowing and I have not experienced any application or flow issues with this marker (don't shake it or you may get bubbles in the fluid though). The pen-style applicator creates even, consistent lines without breaks, so it may not be the right choice when organic looking marks are needed. You can vary line width a little by angling the tip, but if a wider variety of lines is needed, a more traditional masking fluid application method would be better suited.This masking fluid works very well and it handles heat from a hairdryer without bonding to the paper fibers. I've had no problem removing it from Fabriano Artistico 100% cotton cold press or hot press watercolor paper, even if it does take a few minutes to remove thoroughly. The masking fluid lifts completely using an inexpensive rubber pickup tool that I purchased here on Amazon. The lines with this marker are fairly smooth, leaving edges that are much less rough than with other application methods! When a more smooth, consistent line is needed this is perfect!It's worth pointing out that whether (any) masking fluid lifts cleanly is determined more by the nature of the paper being used than the masking fluid. Some papers, especially those made with cellulous, may not hold up well. Even some 100% cotton papers can be prone to paper fibers lifting easily, like Stonehenge Aqua watercolor paper, making them unsuitable for use with this or other masking fluids. While I enjoy using the Stonehenge watercolor paper, I do not use it when I want to use masking techniques, as the paper is easily damaged by them. Also, some papers will handle certain brands of masking fluid well, but not others. That is something to keep in mind when buying this or any other masking fluid. Depending on the combination of paper and masking fluid used, your mileage may vary considerably.I have attached a photo of a recently completed illustration, and a video showing the masking fluid removal, for reference. I created the swirly lines of vanilla on the top and sides of the blueberry bars with this masking fluid marker and I love how they came out. As you can see from the video, the masking fluid can be cleanly removed using a rubber pickup tool, as long as a suitable watercolor paper is used.I will continue to use this masking fluid marker, as it works very well when I want even, consistent lines. In fact, I may switch brands entirely once my normal masking fluid is gone. I think I prefer the consistency of this one and I find the blue color a help, not a hindrance.** If you found this review helpful, please mark it helpful to let me know and help other buyers.
