This pack includes 10 Pilot B2P Ecoball ballpoint pens and 10 refills. The smooth writing black ink gives a writing experience that glides across the page with a medium 1.0mm tip for a 0.27mm line. To help the planet, these pens are refillable and made with 86% recycled plastic components. The B2P Ecoball (from bottle to pen) stands for Pilot's strong commitment to environmental protection along with CO2 compensated status which offsets CO2 emisions during manufacture.
