easy to read
Magic Tag Markers
Labels are vital to successful experiments, but they are in constant danger of smudging or becoming worn. When labels come off, effort and time are wasted. There are few practical solutions. How to best label is perhaps the oldest problem in science.
We haven't found a good solution using hundreds of permanent markers and dozens of labeling machines. Permanent lab markers come off with alcohol, routine handling, freezing, and even water. Tape, to protect the ink or provide a better writing surface, provides only a slight improvement. Running to your desk to print labels becomes a chore and breaks up momentum. Besides, most labeling, the kind of labeling or marking done mid-experiment to keep track of things or steps, is not well suited for sticky little labels.
The Magic Tag Engineering Marker provides permanent writing that withstands abrasion and solvents - from soapy water to alcohol and even autoclaving and freezing!
Forget about the days of painstaking labeling; our Engineering Marker does all the work for you! Use it during any experiment. Magic Tag Markers is the quickest solution for labeling beakers, tubes, bottles, jars, vials, and more, no matter your situation.
Its tough ink makes sure your marker stays put. No more smudges or smears with our quality ink! Magic Tag Markers are a time-saving solution for the scientist with no time to waste.
Works on Glass, Diamond, Metal, Plastic, Ceramic, Fiberglass, Graphene, Enamel, Paper, Fabric, Leather, Animal Hide, Rubber, Wood, Tile, Epoxy, Stone and more.
Solvent Resistant Marker
These markers are truly alcohol and water resistant! Things I've discovered about these markers:
- Ink dissolves in mineral oil and glycerol
- Easy to read with a range of temperatures; I've used it to label autoclave containers, tested it in a 37C water bath, in liquid nitrogen and dry ice
- The pens may explode and cause an uncleanable spill on the floor and down your lab coat
- The ink flows easily and is always easy to read; won't fade as long as you let it dry
I followed some tips from other reviewers that I think are important:
- Keep the pens upright when not in use
- From time to time dab the tip with a wipe to keep it clear and unclogged
- Vent the tip occasionally; I think this could potentially help prevent spills/leaks
Some features that could be implemented/improved:
- Attached caps/caps with clips
- Finer lines. Not sure if it's possible with the way the ink flows out
- Reusable pens with ink refills
- All black or all red packs. Other colors?
I will definitely keep using these pens! Highly recommend if you're ok with a higher maintenance pen

I would highly recommend this product to someone like me.
We do clinical PCR and clean everything with 3% hydrogen peroxide or dilute sodium hydroxide to get rid of DNA and RNases. We also freeze thousands of samples. The markers work well for labeling reagents that come into contact with the cleaners, and the ink also withstands freezing. The moister that condenses on the tubes and containers does not bother the ink at all. I don't have to worry about labels coming off of ink smearing when handling reagents. I wish the tip were finer. The marker tends to bleed, so the writing is thicker than the tip. But the markers are still better than any other marker we have been using. Thank you.
Relative to other lab markers I have used, these markers rock! Most lab markers are pretty bad in my 20-year experience: they both dry out and come off. I've been using my black marker consistently for about three months. The marker still seems like it has plenty of ink in it. My VWR marker would have dried out by now. Further, our VWR lab markers do not write on paper very well because the tip is very dry. But these engineering markers can write on both paper and plastic.
