STAEDTLERLumocolor Permanent CD/DVD 310 CDS-9 Marker Pen Superfine 0.4 mm Line - Black, Pack of 10

I bought these since Sharpie no longer seems to make a "very fine" point for their markers that are "safe for use on CD/DVDs." These write fine on disks. However, not enough time has gone by yet to tell if they will damage them long term.

The trend these days seems to be for the market to sell pens whose ink is purported to be waterproof, but without the guarantee of permanency, which is not good enough for me. In this respect, the Staedtler range has never let me down. The ink contained by this design is virtually unsmearable within a couple of seconds of application. It does bleed through cheap notepaper onto an underlying surface, but when used on less absorbent material the ink stays where it's put, indelibly stuck. Great for addressing envelopes, writing cheques, and doing line drawings, etc.

Overhead projector markers re-branded for the 21st century as CD/DVD markers, these have many uses around the home and office. A good quality permanent marker. Useful for marking plastics, glass and ceramics for DIY, creating temporary labels on PVC tape (for cables, on your mixing desk etc).

I use these pens to write on plant labels and they are very good. Very fine tip and the writing doesn't wash off in the rain or fade in the sun.

Most pens sold as DVD markers are too thick -- fine for the disc title, but useless for providing details of what's recorded.These really are superfine, and write smoothly and precisely on all the discs I've tried (Verbatim, HP and TDK DVD-R, TDK and Digistore BD-R, Verbatim BD-RE).The price is fair, and you don't have to buy a load of colours you don't want.

Great pens 🖊 for work as I’m a phlebotomist and writing on the bottles is difficult because of smudging. No more!!!! these pens dry really quickly and no smudges 👍
