To whom it may concern,
As I mentioned in my previous email on 2/26/24 we never received the Magic Tags and our credit card was charged anyway.
Please get back to me and let me know how to resolve this matter
Thank you
We apologize! The markers were on backorder, and simultaneously, the website crashed, mixing up our order queue. We sent out a free pack of markers to everyone affected and took steps to help ensure that this will never happen again. We hate that our mixup added to your workload. Our primary goal is hassle-free labeling to help make your job easier. We hope the makers are living up to your expectations.
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.
