STAEDTLERLumocolor Universal Pen, Medium, Felt Tip, Permanent Marker, Box of 4 Assorted Color Pens, 1.0mm 317 WP4 (317 WP4 ST)

These work fantastic on sports cards that are paper quality and will work on chrome cards but I’d look into how to prep them so it sticks the best. Good value for the money and doesn’t seem to streak at all.

Very pleased! I was looking for a pen that would be permanent on a waterproof map - and it works great. I have to allow a few seconds to dry but after that, no smearing.

The usual Staedler excellence! My 20+ year old set is finally drying out - in very low humidity San Jose, CA - no other felts last anything like this!

I use these on music CD's and photo DVD's that I make. They don't smudge or smear. Great product.

I purchased these in the hope of replacing the discontinued "extra fine" Sharpie that I used for labeling items in the freezer. I needed a permanent marker with a fine tip but not so fine that it would puncture ziploc bags when I wrote on them. These pens write beautifully and I would definitely order more. They are a little too fine for writing on plastic storage bags for the freezer, but the ink is dark, the points are very sturdy and I think they will last a long time.

Bought these for autographs on sports cards. Great value and will appear to do the job!

These are nice replacements for the Sharpie and Memorix CD/DVD markers that are no longer manufactured. Searched quite a while and found a reference to the Staedtler Lumocolor pens on a disc archive forum, so tracked these down on Amazon. They are a bit pricey but seem to write darker and hold up longer on the DVD surfaces. The Sharpies had a tendency to fade after a while and were not that dark to start with. These particular Staedtler markers are in limited supply on Amazon, so not sure where to find them in the future. There is a fine point version of these that appear to have more availability so could use those if necessary.Some archivists believe the regular Sharpie permanent markers will eventually damage DVDs, so going to use these Staedtler markers just in case.
