Made specifically to fit inside a 35mm Film Pot, or other similar sized container.  These come inside a resealable bag, with three sheets of printed "Rite in the Rain" paper ready to use.

The top of each sheet says "Well Done.  You have just discovered a Geocache.  Please sign this log book and hide the cache again where you found it.  To find out about the sport of geocaching visit:  www.geocaching.com"
