When it comes to eco-friendly pens, the Soho Pen/Highlighter combo is at the top of our list for both functionality AND earth-friendliness.
The kraft paper barrel is made from recycled paper, with PLA Plastic accents (made from corn). With 81% organic content, this is a pen you can feel good about branding your logo on.
And if your logo is multi-color you'll really love the Soho. This is one of the few eco-pens that offers a full-color digital imprint option ($.20 extra).
