Take sustainability to the next level with the Brands U-Eco Gel Ink Pens with Ink Refills. With the environment in mind, these pens are made from renewable and reclaimed wheat straw. And when your pen runs out of ink, reuse the barrel and refill the ink with one of the 8 gel ink refills included. U Brands is looking for ways to be kinder to the planet and has created U-Eco, a line of sustainable writing instruments. U-Eco provides the option for a better looking, better performing pen that is also better for the environment. Lower your carbon footprint and reduce plastic waste.
