OverseasPermanent Paint Pens Black Markers - 2 Pack Single color Oil Based Paint Markers, Medium Tip, Quick Drying and Waterproof Marker Pen for Metal, Rock Painting, Wood, Plastic, Canvas, Mugs

I used this to highlight tool size on the carry case and also to fill in the groves on other tools. It worked well, the fine point is perfect to touch up and highlighting. The bright white color helps it stand out (against the black case). Very easy to use, just shake it up, press down on the tip a few times and the ink flows easily when writing. It's like any other maker of it's size and easy to hold in your hand to write.

These work great! We put up black towel racks and the screws were too long, so we used silver head screws. I needed these pens to paint the screws black. Worked perfectly!

Great pen. No bleed thru, good tip that doesn’t collapse on you. It easily marks hard plastic or black can canvas

It worked exactly for what I needed it to, writes well and smoothly. Beware, however, when shaking it. The pen has a removable nib that I did not know about, so when I was shaking it without the cap on, the nib flew out. Paint ink didn't get anywhere, besides where the nib flew. The nib is pretty great though because it has a larger bullet and a smaller bullet if that's what you need, but just be careful!

nice pens! i'm gonna use them to label my black plastic plant pots and anything else these will work well on!

Good quality and price, works well on my handgun sights.

Very bad. It did not cover the area. I had to go buy a can of paint to do the small job I had..

Received as described. Work well on plastic .No issue expected marking other materials.Dries quickly...
