So you're looking for pens that seal well.

I carry a black Fishscale MaJohn A1 pretty much at all times and it's never spilled on me. I clip it to my shirt as it is a click-pen.

Another great set of pens are Asvine's line and these ones can be clipped or pocketed. I personally love their P20, V126 and the V200. All of these pens seal really well and I've had no issues with them leaking.

Additionally, you could get a LAMY Al-Star or Safari as an EDC pen. They're pretty robust and easily pocketable, but their clip is unbelievably well-designed so they could be clipped as well.

Another method I think helps keep pens from spilling everywhere is to put them in a sleeve. I've got several I'll use but they help keep the pen safe from damage and getting jostled around too much.

Hopefully that helps a bit!
