Epakh Set of 6 White Refillable Blank Paint Pens 3 mm and 0.7 mm Empty Clear Graffiti Markers Acrylic Permanent Marker Oil Painting for Rock Wood Ceramic Metallic Graffiti Round Fine Tip

Work very nice

Terrible don’t buy. Used one and it exploded ink out of the small tip and the larger one just worked like a dried out sharpie. Used Angelus flat black as the paint inside. They are comfortable and the design is sleek, however. Might work better for someone with more patience.

It's true that the paint can blob when you press down--particularly with the small nib. It requires finesse. If you have the patience and want an inexpensive blank marker, then here's what to do.Use one of those rubber jar lid removers to pull one of the ends out. They are friction fit that, while inferior to a good screw-on type, makes them cheaper to produce. I'm storing mine in a bag, but the fit, which is tapered, does seem really tight.Don't over fill with paint as it won't mix properly. If you want to blend colors, mix it first in a plastic cup, then fill the pen below the fill line... replace the nib mechanism, and shake for a minute or so.When pressing the nib to fill with paint, do it once very quickly and watch the tip. You can sometimes prevent the blob this way, but keep a stack of paper towels handy. The lines this small tip produces are beautiful and comparable to the smallest Poscas. The beauty is you can use archival paint or mix your own colors.I recommend using acrylic inks, not trying to thin yourself. I have thinned fluid Golden paints with airbrush extender, but the premixed high flow are already the right consistency. I have also used Liquitex acrylic inks, FW, and Sennelier Abstract inks without problems.I like the nibs on these better than Montana markers (which come in some of the Golden High Flow sets). If you use them with finesse and avoid the initial blobbing, they work great and are a real bargain. I wish they sold in larger sets with quantity discounts. I purchased more...

EDIT: You can make these work if you modify them slightly. The main problem with them turns out to be vapor lock -- the body is rigid, and air can't get in as you try to dispense medium, so nothing tends to come out. If you pick one tip to keep, you can drill a small hole in the other end (but where it will be covered by the cap!), and then if you take both caps off and use the other end, the medium will flow out of the pen.The marker tip is still not the right material for a marker, much too rigid, but these work acceptably (for me) with this modification.These two-sided refillable pens have one end that has a hard rounded tip and one that has a much smaller nozzle-type tip, almost like a frosting bag might have. They feed from the same reservoir and have their own caps. You can pry or pull them out, and they seal well.Each end has a valve that opens when you push down with the tip. The springs are stiff, and on soft material you may not want to press directly -- maybe keep a dish or bottle cap nearby to use as a surface for activating a bit more flow. Flow is very tricky. The sides of the reservoir (the main body of the pen) is rigid, so you can't finesse it by squeezing. The larger rounded tip doesn't really wick at all; fluid flows over it, not quickly.I tried these pens with two kinds of paint, a glue, a lubricant, 90% alcohol, and iodine. None of them flowed easily, although I really thought the last two would. The amount dispensed with a push on the tip is very small. The pens seem well made, but I'm not sure if the design is a bit off or if it's just not obvious how they were expected to be used. I don't think I could possibly put paint in one of these and, say, write something as if using a marker. Dabbing dots is the best I could do. I'll find another pen design.

After reading a few negative reviews I hesitated about getting these pens (pack of 6), but I am glad I bought them anyway. The acrylic ink tends to be thick and if you depress the tip a little too hard/much, yes, the amount of ink will be excessive, a big drop you don't need. Requires precision and just the right amount of presure. I still need a little more practice and a steady hand myself. The server book I made with the name on it in silver (I used the refillable pen with acrylic silver ink on this project) turned out better than I expected. Please refer to the attached photo. The only down side (but doesn't discourage me from getting another set) is that it seems to be a single use pen. My assumption is based on the fact that I had to push in the tip section into the barrel, NOT the SCREW IN type I expected. DO NOT push the tip section into the barrel WITHOUT its CAP ON to avoid damaging the tip, and do not lose the bearing. 5+☆

The media could not be loaded. Awesome quality dual tip pens.. the only issue is that the middle cartridge doesn't accept either tip being pushed in by hand. remove the round tip then hit the top of the cartridge with a hammer while depressing the cap to the fine point tip into a rug. then you can fill the pen, making sure the ball is inside of the cartridge, after filling the pen you can put the round tip applicator into the cartridge and hit with a hammer to fully seal.

The refillable paint marker doesn't work. First, it's difficult to remove once you have it locked in place. My guess is they are one time use. Next, for the smaller tip, the ink doesn't come out on its own. You have to push it, however, if you press it down slightly a glob comes out but doesn't travel to the tip. If you push it harder then an entire puddle occurs. The larger tip doesn't work at all. I've pushed it all the way down and nothing came out. I'm not sure if the acrylic ink needs to be diluted but it definitely doesn't work as is.

works for my Rocketbook cleaning application
