When we participate in sporting events or mingle at social gatherings it is possible to lose track of our water bottles and/or beverage cans, especially those served in containers that are very similar or identical to a container from which you are drinking. Thus making it difficult to identify your drink. This carries the risk of transmitting an illness, such as meningitis or the common cold or flu.

Thus making it difficult to identify your drink.  This carries the risk of transmitting an illness, such as meningitis or the common cold or flu. The Container Identification Scratch System, or C.I.S.S., is a fun way to make sure you always know your drink from others. Use it at sporting events or at a family gatherings and reduce the waste from forgotten drinks. Simply scratch your number from the C.I.S.S. label and identify your drink.  For more information please contact Bob Gold at Ciss.bob@gmail.com
