That's good to know, I have been going off of my BDU's and have been able to fit a cigar in them. I would have to say that the majority of the pens we send over are slimlines and will fit any uniform. Thanks for letting me know and be safe brother.Nice pens, on a side note, you might want to be careful with the styles that you send over there. I can't fit anything thicker than perhaps a modified slimline or the classic fountain from woodcraft in my ACUs.
