Epakh 4 Pack Refillable Paint Pens Empty Acrylic Touch up Pens for Leather Dye Permanent Clear White Marker Pen Fine Point Markers for Rock Painting Wood Ceramic Metallic Graffiti Drawing(15 mm)

I was more than a little impressed with the quality of the pens. Very well made, extremely heavy duty build. Will probably last for a long time. I used one of my pens to fill it up with dykem layout fluid, which is an alcohol based ink or dye to stain metals for laying out measurements and patterns. Works perfect with no leaking or evaporation at all. These are made from very thick plastic, not thin and cheap at all. I'm extremely happy with this product and would recommend this to anyone who needs a fillable marker for their art or project.

These are great for keather dye.

These work well for using with herbicide to apply onto freshly cut stumps. They have lasted quite well with pretty heavy use. They do have the oddity of a reverse thread for screwing it back together after filling (the opposite of right tighty 😵‍💫).

Much sturdier than I expected and the caps seem to seal quite well. I have had one in the shop (no climate control) for several months now. Filled with layout fluid, basically just a really thin lacquer paint, it has not shown any sighs of drying out. At a price of $2.50 a piece, at time of purchase, I'm not sure what I was expecting but these exceeded it and are certainly suitable for a tough life getting banged around in the shop. Makes applying layout fluid super easy and convenient. Way better than a dobber.

I put leather dye in these and use them for edge dying. I wish I had found them sooner. Before I found these, I was going slow and crazy losing my mind. These don't leak and work perfectly! Highly recommend.

Any water based liquids will change color due the steel balls rusting.

5 stars! I am a leather worker and was looking for something easier to apply edge dye. These seemed like they would work, but I was not quite sure because they are not a name brand. I took a chance on them, and it paid off! These little markers are game changers for dyeing the edges on my leather projects. I used one of them to put my Tokenole burnisher solution as well and while its a little bit thicker, it still flows through the felt nib. I am thrilled with how these things work. I have not had any leaks at all either, and that was one of the worries I had before buying them.One thing to note on them is that the cap has reverse threads, so when you go to try and take the marker apart to begin with to fill it up you have to twist it like you were tightening it, and reverse when putting it back on. could not be happier with these markers.

Had high hopes for these. They were sturdy material and looked like quality. Until I opened them. Lids were difficult to remove. They didn't screw off well. Which was my first clue. Added liquid then couldn't get the threads to align and go back on. The marker tip section never sat on it well. Ended up falling off multiple times during use. The foam portion kept receeding into the lid, so it was more of a smear result than anything else.Ended up losing the top with the chisel tip during use. Literally. It fell off and rolled away someplace. Cannot find it.Throwing these away. Not worth the frustration.
