I downloaded this mid-game, along with the Modern NPC Pocket Contents by the same company, and used them right away. They are excellent charts.

Some of the pocket contents might inspire creative ad-libbing DMs to assemble an unplanned adventure around one item being in an NPC's pocket.

This is one of those things that you'll have no idea you needed until you've used it. I love it.

Thumbscrews? Inflated pig bladder? This download is delightful fun. I can't wait until I have an excuse to add some of this color in on my group of adventurers. Many of these items aren't going to fit until a pocket, but that makes the list useful for fulling up those random pouches that an npc might have, as well as haversack-type bags.
