SHARPIEIndustrial Permanent Markers, Fine Tip, Black, 36 Count

These are great for items that may get wet or exposed to certain chemicals. They work great

These work great! I always need one of these, but they're never around. Now, I have one every time I reach for one!

I am a pen snob. I will never go back to regular Sharpies or any other permanent marker. Crisp clear ink and firm felt tip makes writing clearer than other markers. It allows you to record the date food was opened on slick or damp with condensation plastic packages, like sandwich meat from the refrigerator section. Great for writing names on plastic cups, making signs, labeling personal items. SUPERB PRODUCT!! I have purchased 3x and shared with family and friends. Yes, I am that girl.

These work great

These Sharpie markers do write better than the regular black colored markers, but I do think Sharpie can do better with markers labelled "Industrial". I use them in a clinical microbiology lab to write on the plastic part of agar petri plates that we streak bacteria onto. They don't write nicely over plates that have some condensation, so they are not as waterproof as they claim if the plate is already slightly wet. If the writing gets wet though, it is pretty durable to not fade out. Heat-proof is also very good for my use in that mostly putting test tubes in a heated water bath or dry heater, the ink does not fade readily. I usually have to wipe the plate off with a towel before writing on any damp or wet plates.However, they are not very long-lasting. After writing on several tens of plates a day sometimes a hundred, the marker maybe will last about a week or two before it become dull or spotty. I've noticed though that the blue color "regular" Sharpies have some sort of more potent dye because they outlast any other color that Sharpie produces. We use blue markers regularly at the lab for that reason. They show up well and are more potent than other colors and types of Sharpies.I would also like to suggest to the Sharpie gods that they should try incorporating the "click" pens for these types of markers because in the industrial or professional lab environment, we do not have time for capping and re-capping these things every use. A simple click pen would be a nice twist to this. They will dry out quickly if left uncapped for a minute or two between tasks.I would continue to purchase these and also the blue regular Sharpies for my use in the lab until I find a better product.

These are opaque markers, a dense, dark black that I love. I use them to draw and color in. They don't last as long as I'd like them to, but I don't know how they compare to other markers in their category because I've only ever used sharpies when I want marks that are permanent. I use them on surfaces that I then wash with warm water, soap, and a little scrubbing and the marker stays on through many washings. The marks do fade of course, under these conditions, but they never wash off completely, which suits my pruposes perfectly.

Easy to use work well on different materials

Para el trabajo

Arrived as scheduled and perform as expected.

Los uso constantemente y como sabrán te los roban regularmente, conviene el precio. Estos son calidad industrial en la etiqueta dicen que soportan altas temperaturas y condiciones poco amigables, no los he puesto a prueba en condiciones extremas pero en general han funcionado muy bien.

Tiefschwarz, qualitativ hochwertig, hält auch gekühlt bei Minusgrad, so wie bei hoher Hitze! Entgegen vieler anderen Marken, die wir bisher getestet haben, haben sich die Industrial Permanent Marker als die besten gezeigt. Sicherlich kann im privaten Gebrauch auch ein günstiger Marker die Arbeit verrichten, aber wenn es professionell sein soll, dann greife ich auf diese Marke gerne zu!

Good buy and promptly delivered
