Super Met-Al Squeeze Action Metal Tip Marker, Yellow (3 PACK)

I’ve been using these pins for well over 20 years they last an incredible long time I use them every single day writing on every type of surface usually marking things for easy reassembly or even marking nuts or bolts for tamper resistance evidence.They write on just about everything from oily hydraulic hoses to intake manifolds and even exhaust manifolds/ the color will white out with high heat but still readable with the high temperatures.I’ve tried just about every color and for my purposes yellow is the one that works bestI’ve even mixed some of the colors together to get my own unique blend or color for tamper proofing

Any color, doesn't matter. I use them in my shop on a regular basis. They work well. This outfit did sell ink refill bottles. I can't seem to find it any more and upset by that. Now you have to constantly by when it's empty. The throw away economy we live in.

An item I'm familiar with. No complaints.

Works well, bright color.

Worked great
