SEVEN SERIES
Seven Facets of Time
The Seven Series by 22STUDIO is inspired by the seven-day week's perpetual nature. The seven sides represent this artificially created structure to our sense of time. These striking facets are formed through a 14-day curing process in a specialized chamber—strengthening them and ensuring that they withstand the test of time.

Meet the Studio
"In 2005, my wife Yiting Cheng, and I founded 22STUDIO to satisfy our enthusiasm for concrete's raw, exposed beauty. Inspired by the works of Japanese architect Tadao Ando, we wanted to create personal products that transmitted the material's honesty and transparency."

Amazing Pen
This pen is amazing. I love the way that the concrete gets darker over time which contrasts really nicely with the metal. Not a huge fan of traditional ballpoint ink so I switched it out with a gel ink refill. I love the weight, feel, and balance as well. It’s fun to spin around and fiddle with.

Excellent
The only thing which I would like to mention Is that you cannot attach the cover to the original pen When you are writing


My New Favorite Ballpoint
I love this pen! I own three of their screw-cap pens, another retractable, a fountain pen, a mechanical pencil and a drawing pencil. You get the point, I like these concrete writing tools. They are stylish, well designed, and well balanced. Although they are the same size as most pens, they have a substantial heft. And I like the grip of the material in my hand. This particular design is smoother than previous designs I have purchased (the others have more "tooth") Refills for all of the pens are very easy to come by. Mine is currently loaded with a fine point blue gel. This pen should last forever!
