Zonon Multi-purpose Deep Hole Marker Pens Waterproof Deep Drill Hole Long Nib Marker for Carpenter Woodworking Hardware Machinist Tools, Red, Black, Blue(3 Pieces)

Every now & again, I have to mount equipment onto exterior walls with deep, small screw holes. I normally use a Milwaukee Inkzall, but it can be too big for the mounts with those smaller screw holes. When I used this for the first time, it fit perfectly. And when I removed the mount, the marks were very visible even with what I thought felt like light touches against the wall surface. This item was exactly what I needed.They feel a little delicate compared to other markers like the Inkzall. Therefore I will not be keeping them in my main tool pouch. Instead, I plan to keep them in a tray of my drill box where they will be secure & undamaged until each time I need them.

I have been looking for something like this for a while. Works great for small holes and tight areas to make lines and drill holes. Got some for work as well.

It’s surprising how useful a pen with a longer tip can be. These work great. Good value for the money!

A regular pen or pencil has a thicker end so you are unable to get right beside a ruler or a 1x piece of wood without holding it at an angle. These pens allow you to hold the pen straight up beside your measuring tool for an exact dot or line. These pens are a perfect addition to my art studio and work shop!

Finally someone made it. Perfect for DYI projects.

I use these for marking steel and metal work for welding projects. I like the long shaft length as it allows me to use a lot of varied thickness items to mark straight edges or measuring. Take care of them as they will dry up if not capped. Not unreasonable, just clean up at the end of the day

They wipe off and run when marking on still and aluminum

Like the concept of the reach depth but the blue seems to bleeding and leave a wide line in wood. Works well in freezing temperatures.
