Calendars are no longer a piece of paper that can be torn off like in the past. This bold design turns the calendar into a desktop ornament that goes through our lives year after year. The designer uses the characteristics of the magnetic ball and matches it with an external ring to form this calendar. The point where the ball points to a fixed point on the ring in the air is the month, and the other small ball attached to the horizontal rod is the date. This black technology magnetic ball is not only a calendar, but also a unique furniture ornament.
