Look no further. Here's the water-tight container you've been looking for. In fact, here is a set of three of them: see-through (for safety) and conveniently sized. This nested set of small boxes arrives ready for you to fill and hide. 

The info on the lid is integrated into the plastic (i.e. not just a sticker and so it will definitely stay on).

Description: Features: 4 easy-to-use closure snaps; marked clearly with the words "Official Geocache"; dedicated space on lid for pertinent contact info. This set includes 3 sizes: 0.24L, 0.5L and 1.5L.
