Lumocolor Universal Pen, Medium, Felt Tip, Permanent Marker, 1.0mm, Black 317-8

Excellent markers! Love these for note taking. Tips are durable for fine point precision marking. Not the AR marking pens for optical use, even though they look similar. Great buy if you want to give your optical manager a heart attack!

Being left handed I am constantly smearing anything I write on that are laminated or dry erase boards. Then I remembered that while serving in the military 25 years ago, that we always used what we called alcohol pens to mark up our laminated maps. These would never smear, even during rain soaked days in the field. It took me a while to find these since I was looking for "Alcohol Pens" but I finally did & I have to say that these are worth their weight in gold. They come in all different sizes, super fine, fine, bold etc, & many different colors. The only downfall is that I have never been able to replace just 1 color. It seems they are only sold in package deals. These are great for businesses that used laminated calendars or tracking logs that they don't want just anyone to erase. The only way to erase these are to use alcohol, wipes or spray on.

Used Staedtler in the Army in all kinds of weather and use them now. Best indelible ink markers on the market, especially for fine tip and written sentences. Works in all weather.

Durable and vibrant colors

I love Staedtler pens and prefer them to Sharpies...but they are hard to find and I'd only found fine point Staedtlers in the past. These medium point pens are a great find! They have all the great benefits of Staedtler with a nice sized medium point. The main reason I prefer these over Sharpies is that the ink lasts much longer. They don't dry out with age because they can be left with the cap off...which I don't advise...but if you do temporarily misplace the cap your pen will be fine for a few days until you find it. On some of my pens it says you can leave the cap off for 14 days. I have Staedtler pens sprinkled all over our house. Because of the better ink, I've found that a pen that's used only occasionally will last for years versus Sharpies which will dry out, even if it was brand new, after just a year or 2. Staedtler Pens are made in Germany and are refillable too...although it seemed to me that the refills cost as much as new pens did. This order came quickly from France. Excellent seller and speedy delivery.

Colors are bright and vibrant ~ but it bled through my journal pages. This set won't work for why I bought it.

I purchased these markers a few months ago. They are fantastic. I usually use a sharpie, but although they are supposed to be permanent, they will fade or disappear over time. I am using these mostly outside to mark my plants. I write on plastic bread tags and then attach them to the stems of my plants. Great for fertilizer reminders, types of plants, etc. I wouldn't hesitate on buying this product again. I've only used the black marker, but I'm sure the colors are nice and vivid and would work well on a variety of projects.

Write/dot ink perfectly on glass, which is very helpful for me as a pathologist to mark areas of interest on tissue biopsy glass slides. This is now the only brand I use, and I buy a pack for my new fellow trainees every year. Wish I could get a pack with an extra blue or green or purple in lieu of the brown, but other than that, these are perfect. They write every time without hesitation. No dotting it on paper to get the ink flowing...at least not until after a year of daily use for me (I suspect shorter life if writing on paper instead of glass). After a year or so of constant use they start to require dotting to get ink flowing)...I just toss them out at that point and buy a new pack. From glass, they can easily be removed with alcohol wipe.
