Are you planning to have them use the back of the instruction sheet for notes? If they need to leave a note somewhere, that would require them to tear up and/or leave the instructions.

So I second adding some blank paper.


Does the keychain light have an actual on-off switch or is it push-button only? If it has a "stay-on" mode, it can free up the hands, and if you add a safety pin, it could be pinned to a shirt/jacket/whatever. If it has a decent amount of "scatter", it could eliminate the cyalume, too.

Second to adding safety pins.


It's trivially easy to fold duct tape around a business card. Make your own tape packs, and save a bit of money?


Are you going to supply replacements/refills for used items?
