So weird that I just noticed this now. I just returned from Fedex/Kinkos a few moments ago addressing this issue.
You get yourself some business cards, say 20-30 of them. Go over to Kinkos and for $1.25 each make laminated luggage tags out of all of them. Included free is your "jelly" rubber band thing that attaches them to luggage or whatever.
Each article from the hunt gets one of these affixed so they go quick and you always miscalculate too conservatively. Skulls get them, shoulder mounts get them, panels/hides get them, tusks/teeth/tushes get them, separated legs/hoofs/feet get them.
If you don't want a mess up, don't rely on a PH living in a 3rd world country that doesn't have kinkos around the corner to try and handle all of this. Bring your tags, affix it to all the trophies, be happy when things work out great.
Why plastic laminated tags with plastic looped bands? Doesn't rot. Doesn't get soaked with blood. Doesn't rub off when hides are moved around. Resists salt. Etc.
Total cost for 24 tags: $30.
