Ensso's original Uno Pen is delightfully minimal, with a twisting cap protector that doubles as a grip. Since its launch, the company has received countless requests for a version that used standard Pilot Hi-Tec-C refills (the original uses smaller Coleto refills). After a year of development, it's here in the Uno XL. Like the original, it's made in California with 100% stainless steel, and has a twisting cap protector just like the original — this time with a knurled finish for added grip. Measuring roughly 5.3" long and weighing just over an ounce, it's an ideal desktop companion for the travel-ready original.
