Have you ever wondered how long you spend reading? No, us neither. But obviously someone has, otherwise this bookmark with a built in clock that times the amount of time you read wouldn’t exist.
Measuring 19cm long and 4.5cm wide, the Mark-My-Time bookmark is powered by a single replaceable watch battery, features an LCD clock with both stop watch, cumulative timer and countdown timer modes. For $15 bucks, it’s probably something parents who want their kids to read more than they play video games, and want a way of quantifying that time.
