These have a slightly more 'scratchy' feel to them compared to the pens I used previously, but you don't notice it after a while. I've used 3 so far and have had no problems with ink flow or with smudging. In fact, my previous Papermates suffered with ink flow dropping in and out when they were coming to the end - these just run out and that's that (so no manic shaking of them 'cos you just KNOW there's some left in there...! Or is that just me - 'cos I'm tight and want my money's worth...?! LOL!!) I use them daily addressing padded envelopes and they're absolutely fine. They are excellent value for money.
