The eternal struggle: you put down your cup for 5 minutes at a Super Bowl party, and when you go to pick it up, there are at least 6 more identical ones. You can put your name on it, but we all know nobody can read cup writing. Enter Cup Flags. They take little time to print, are flat and easy to write on, they actually stay on your cup (unlike suction cups), and you can reuse them. If you put some Scotch or electrical tape on them, you can use dry-erase markers, and use them over and over again!
