Review on IMT 6 Pack Tungsten Carbide Tip Scriber Aluminium Etching Engraving Pen With Clip And Magnet For Glass, Ceramics, Metal Sheet by William Fowler

This works great. I am a tradesman who trysts a lit of different things out and while I use it little, it does a fantastic job. The only issue is the brass like magnet on too looks cockeyed and almost wedged into the top of the pen. Also, do not let this fall out of your hands while on a ladder. One of mine fell and hit the magnet. A portion if the magnet literally shattered. It's all cleaned up now though but it is fairly fragile. However, to keep in your EDC bag for occasional use, these scribe pens are the tits.
