KrinkK-51 Black Alcohol Based Marker, Handmade in USA, Precision Control Tip, Bold & Durable Ink, Ideal for Sign Making, Illustrations, Calligraphy

I use these (black and other colors) for fast-paced abstract art drawings on paper. I've experimented with other types of pens & ink, and these, by far are the best. I do wish they were refillable, but regardless, these put other pens to shame when it comes to needing lots of bold ink in a hurry.

great for tagging trains in manhattan

Excellent to cover large spaces. Works perfect in smooth surfaces like metals, alluminum and glass. Its also great that you can refill it.

My son loves to do graffiti style art in his sketch books. This was a Christmas gift for him which he was stoked about. BUT after a few times of use, I noticed his hands covered in it and asked what happened. It was all leaked into the cap and also got on my couch! So yes it works nicely but it leaked everywhere!

The paint flows smoothly and covers well. The paint is opaque and the marker is well made.

Great product

I regularly use this brand and it’s amazing! This latest one though was very disappointing. Tip gets stuck and dysfunctional because the paint inside is very very thick and parts of it is clumped. I never experienced this problem before. I tried to return it however Amazon told me to deal with the seller directly. At that point I gave up because I didn’t want to deal with it.

I LOVE IT!!!!!!
