Not sure what to say about permanent markers they are black chiseled tip so we ca write bold or narrow they last as long as expected since they are used in a sometimes oily environment. We use these to notate filter change dates no our equipment and vehicles. I do like the sort of squarish design easier to grip and less likely to roll away.
We use these at the Food Bank to mark out bar codes on donated food items. They last well even when used on damp labels. The price can't be beat esp for the quality.
These are my new go-to markers! Just a nice true black ink with nice sharp clean edges. I definitely recommend this value pack! I had tried these out before buying the 36 pack so I already new how great these markers were…Believe me just go big and get the 36 pack.
This is the best marker I've ever used. Its coverage is complete and non-see-through with the first stroke while other brands require several layers to achieve the same coverage.
