I really wanted to like these pens because of the rubber grip they had, but as a left-handed person, I just couldn't stand all the smudging from this pen. My side of my left hand is practically covered in ink once class is over.
Like all super glues, this can go horribly wrong if you're not careful. It's very effective at holding things together and does what a good super glue should do. The single use size is handy when you're out and about and you need something glued together pronto!
