Concrete Desk Organizer
It's 10 inches long and strong. Oh, and by complete happenstance, this Concrete Desk Organizer is too. The hefty holder has a mostly stark, industrial aesthetic, with a softening sine wave flourish on its business (card) end.
The Concrete Desk Organizer has notches to fit 4 pens and a slim phone, along with your grip business, membership, appointment reminder, and coffee shop punch cards.
