SHARPIEOil-Based Paint Marker, Medium Point, Blue Ink, Pack of 12

They work

I use them at work to write on pipe. I like the color because it’s bright and stands out. Only thing I’ve found wrong with them is when the weather was fluctuating from cold at night to warm in the afternoons they would seem to leak. If you keep them in a controlled environment I’m sure this wouldn’t be an issue.

Good price compared to buying separately

Works as intended for torque connections

Bright BLUE!Perfect for marking STEEL

Ink takes a minute to drop down - however once it is saturated, it works fine.
