This is fantastic! I, too, would like to change all the pens at the office. A dream, I know. Where do you buy these?

the pens in your office won’t biodegrade, though, so i’m not sure what you will do with them after you have replaced them. Maybe just keep using them and hold off on these until you actually need them, if you want to be environmentally friendly. Or even better, get a refillable pen that you don’t ever have to throw away.
