It can take up to 90 to 12 seconds for the ink to dry, depending on the surface and room temperature. We typically label items and give them a few minutes to dry before use. The Engineering Markers are still the quickest way to label things.
Store the markers tip-side-up.

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.
I just purchased five packs for my lab! We primarily use the markers when culturing bacteria and maintaining C. elegans. They are shipped by Amazon, FYI. Shipping is fast. We are throwing out our Sharpies. Most of them stopped working only after a couple of weeks.
