ArrtxTop Valve Action Marker Pen, Set of 24 Colors Simptap Acrylic Paint Pens, Extra Brush Tip, Water Based Paint Markers for Stone, Glass, Easter Egg and Fabric Painting-Arts and Crafts for Adults

I haven't used these long enough to say if they will stand the test of time, but from my usage over the past month, they are just what I've dreamed of! I love the tip, the way the paint flows and the size of these brush markers. I wish the white was more opaque, but layering works!

I enjoy using them but I don't have a problem with a few leaking. I put some paper towel around the bottom with the cap for the button on and taped it. Since then no paint has spilled out, I did what the instructions said to all of them but I guess you just need to keep an eye on them.

As an artist, I absolutely love these acrylic paint pens. Yes, they do require some patience when you're first filling the ink into the nib, but that’s hardly a major obstacle for anyone who knows how to handle their supplies. The key is paying attention to the window and taking your time. If you do that, these pens will NOT overflow or leak.The colors are vibrant and rich, with an impressive range of hues, including two gorgeous metallics. I own both Posca and Arrtx pens, but these surpass them in every way. The ink flow is superior, there’s a broader selection of colors, and the nibs are more precise. These are fantastic quality pens, and when used properly, they deliver amazing results.

So far, the pens have good strength of color, ease of flow and use, good value

Listen, I love the juiciness of these. However, even when I stored them how it was recommended, the ink separated BADLY. There was always this ugly yellow color that I would have to wipe off over and over before I could use the marker. I just want to take the lid off and use my markers, but these don’t work like that. I used these almost everyday so they didn’t separate from not using them. I created some beautiful pieces of art with these, but now that I’ve used a few up, I decided to try a different marker brand. The original arrtx markers were nice but not as juicy, which is what I look for.

I was looking for a white paint marker, or something with which to lay down an opaque, white mark for highlighting my watercolor artwork. And though gouache works well, it will ruin my brush unless I'm careful to clean it immediately after using. What I really needed was something like an acrylic paint on a brush tip. On a YouTube recommendation, I discovered Arrtx. This is almost perfect for my needs. The brush tip allows me to apply the acrylic in a very fine line, although I would appreciate something even finer. But at this point, I'm happy.Hopefully the company will soon sell the white acrylic pens as singles instead of in a pack of 24. The caps snap shut very securely, so I'm not concerned about any drying-out issues. And following the directions, they're very easy to get the paint flowing if using them for the first time.As for opacity, even the white paint is quite opaque over a black surface. And if you need to apply a second layer to make it 100% opaque, there's very little waiting time because the acrylic dries pretty quickly.

I love these! This is my second set. I got the first set they released of these and liked them enough to get the biggest set.The ink flow is good and I like the brush tip on the markers. You will have to shake the markers before using them as the ink separate. The white ink works really well.I do wish there was a better variety of reds and blue greens. None of the blue greens are super dark. The reds are still more on the cooler side. But this is fine as one can supplement such colors from other brands.

Excelentes!!!!!!
