Review on Optimized Welder's Marking Pencil by Larry Boyd

Used. Both when using a torch and when welding. I used it to leave my mark. Do not go! Soapstone worked much better. I have to say I was really disappointed. I bought three packs of three pens each. I don't care about refunds. I'm too busy for all the fuss and red tape (which the seller surely relies on to make a profit). I just hope I get in touch with someone before they spend their money and get as frustrated as I do.
