OK, no picture......can add for the imaginationally impaired if forced....
Wifey had large magentic white sheet......(as in 12x8 inches) I cut 2x2 pieces, and with indelible marker write beer names on them, then slap above faucet. When keggie kicks, put on side of keggerator/keezer until next time. One sheet makes a bunch of them. Not sure where she got it......I'm thinking Staples or Office Max......
