Did you know that about 100 million disposable pens end up in the landfill each year? You can start your Earth Day celebration early this year by reducing the amount of waste you produce with the Seven Year Pens from Seltzer Goods. Inside this pen is an over-sized cartridge that holds up to six times the amount of ink inside a regular BIC pen. A Seven Year Pen can write 2 meters per day for seven years. There are a variety of colors and designs to chose from; each is $7.50.
