STAEDTLERLumocolor Permanent Fine Black Box of 10 Markers

I work as a medical laboratory scientist, so I need a fine-tip marker for tons of uses. My previous lab was stocked with Sarstedt markers and I loved them, but they are way too expensive. These are the perfect replacement. They write well on glass, plastic, labels, gloves, almost everything and they don’t smear! When writing on glass, the ink doesn’t “bead”, it’s a solid line. These work well even on cold items. Typically, the condensation really makes it difficult to write on a label, but after just wiping the label against my sleeve, these pens write perfectly and dry in no time! Will definitely be repurchasing again and again!

I tried many markers for adding signatures to fabric to be used in a memory quilt. This marker The Staedtler Lumocolor was by far the best, with the least bleeding and the least fading with repeated washing. This vendor was the most economical out there. The tips held their point very well, I had plenty of pens but none of them wore down needing to be removed from use for the project. It was also easy to use for applying the signatures. I simply ironed a piece of freezer paper to the backs of the signature blocks. Be sure to provide some practice pieces for people to learn how to sign on fabric! I also had a semi-soft smooth for a workspace for those signing.

These pens are by far the most versatile when it comes to going over the wax bloom of colored pencils without the nib becoming clogged. I have used them for years and will continue to do so for most of my line work.

Just what we wanted

We use these for labeling costumes. No bleeding, legible. Even better than Sharpie rub-a-dubs. Also good for writing stuff down. When I really think about it, it's my favorite pen.

I needed a pen to either draw on paper with and water color over or water color a picture then draw over it. It is a wonderful tool to add to my art collection

Lines were much thicker than I expected due to online images different pen lines on charts. Also seems to spread when used on paper and goes through to the other side. When I asked to return the item for a refund or exchange I was told it could not be done due to "flammable" item. They shipped it to me, that does't even make sense. Would not buy this product again. Beware of thick lines.

I prefer this Stadler fine tip marker to those made by Sharpie. Good for permanent writing and more visible than Sharpie fine point. Shipping took about a month, but it may be a supply chain issue. Also, the product arrived with the pens out of their box, loose in the packing envelope, with the box folded flat in the envelope. All was well with the pens, but quite odd.
