When your to-do list is a mile-long and your schedule is booked solid, you've got enough on your mind to deal with — the last thing you need is a calendar covered in kittens to distract you. So South Korea's O-Check Design Graphics created this incredibly clean monthly planner that doesn't even have any calendar lines printed on it. Instead, they're all embossed so they're as subtle as possible.
For just $US16 it comes with 32 pages of blank monthly calendars so you can write in the days of the week as they change from month-to-month, and it will be at least a couple of years before you need a replacement. The planner also seems like a doodler's dream, giving you an almost completely blank canvas to scribble notes and sketches. [Omoi Zakka Shop via Better Living Through Design]
