Review on ✍️ Anteiwa Tungsten Carbide Scriber Marking Tools Set - 3 Pack Aluminium Etching Machinist Pen with Case, Magnet, and Clip - Ideal for Glass, Ceramics, and Metal - Includes Extra 3 Replacement Marking Tips by Carlos Whitfield

These are high quality pens. I only use them for light marking before cutting or engraving, but the nibs are solid and hold their shape and I'm very happy with them. I haven't had a design like this before - I used a 30 year old one-piece pen that I always had. This one, by the way, most likely wasn't tungsten carbide - maybe iron or something. Anyhow, it's lightweight, easy to store and does what it's supposed to do. Satisfied. highlighted. It's good to have three! Each is packed in a separate plastic case. It is also excellent as a filling for stockings.
