Outstanding markers for laboratory use. Very robust and durable.
Arrived 2 weeks sooner than expected (for an international shipment. I use these markers in a laboratory. Markers write perfectly on plasticware, and writing is completely resistant to 70% ethanol (alcohol). No smudging or bleeding ink. Tips are strong and durable. Ink lasts for ages (pens dont dry up quickly). Will definitely be buying again.

Not alcohol resistant
I bought this to write on cyrovials... as they are supposed to be "Alcohol resistant cryogenic permanent markers". I was excited to test them out and as it turns out they are not at all alcohol resistant. One spritz with 70% alcohol and the marker completely washed off the plastic cryovial.

Not fine tipped
I am a repeat customer. Originally, they were wonderful. The ink was dark black and alcohol and acetic acid resistant. They are now fat tipped and smear easily. What happened?!!

These markers are NOT working at all. I wrote ...
These markers are NOT working at all. I wrote text on my PCB boards for serial numbers. It is not very dark as Sharpie marker. Overtime, several days, they faded out quickly, even without any alcohol. With alcohol, these text can be erased immediately on the PCB. These are purely junk, not as advertised for scientific labeling. They should not sell markers. The Sharpie permanent mark is much more uniform and last a lot longer than these. Now I change back to Sharpie permanent markers.
