Paper Mate InkJoy Gel Pens - Medium Point (0.7mm), Black Ink, 12-Pack (1951719) - Perfect for Office, School, Note Taking & Journaling

I love these pens. I use them for drawing, sometimes writing. The ink dries super quickly so I don't smear my work which is more important in drawing than writing because I often drag my hand across my lines. The pen bleeds when held against paper which is useful for dotting and detailing. It even causes nice line-weight variation.One issue with these pens is that they don't last too long. You can visibly see the ink going down in the well day by day. If you use these pens to write school notes, they will only last about three weeks. They last for about two sketchbooks for me.It'd be nice if they made these pens refillable (they cannot even be taken apart), because their bodywork is nice and it'd be better to not have to spend roughly $1.5 per pen.Despite their poor longevity, these pens are amazing and are the only tool I use in my main sketchbooks now.
