Oh my, this is a real prize for a stationery junkie like myself. This ingenious calendar is beyond cool. I love it!

Spanish designer,
Oscar Diaz explains how his calendar works: “
The ink is absorbed slowly, and the numbers in the calendar are ‘printed’ daily.
“One a day, they are filled with ink until the end of the month. A calendar self-updated, which enhances the perception of time passing and not only signaling it.”
It’s just pure artistic genius. Oscar Diaz I salute you and I’m in love with your calendar.
