The most common procedure to make the casualty cards water-resistant is to use laminated paper. This method has a downside: laminated paper can be compiled exclusively with a marker. Markers, on their side, are sensitive to atmospheric conditions (try to write on a wet plastic surface) and the heat that is generated inside the IFAK (especially in desert environments), exposing users to the risk of malfunctions when the marker is needed.
We worked to solve this subtle but fundamental problem developing our TCCC-CARD: it keeps the properties of plastic, such as wear resistance and waterproofness, but at the same time allows the compilation by the pencil, the safest and most reliable writing tool ever.
