Perpetual Ring Calendar by Athlone Designs

I love searching each year for an original paper calendar to hang on my kitchen, but let me say I would love to have a calendar on my office table that I wouldn't have to change every year. That's why I loved so much this Kickstarter campaign, a Perpetual Ring Calendar by Athlone Designs.

The ring has an innovative design with a 7-sided heavy steel day star surrounded by a Titanium or Aluminium ring.

You can use the calendar can also be used as a ruler, since each day is spaced exactly 1 centimetre apart.
