ACME Studio Eco-Pens
For you, to write thoughtful thank-you notes to everyone who has made your holidays a bit merrier: We at MNN just can’t get enough of Eco-Pens, biodegradable (they’re made from corn starch plastic) ballpoint pens from the writing utensil wizards over at ACME Studio. Featuring an ergonomic three-sided grip and a nifty porthole that lets you check the ink level, the pens, when properly disposed of, will biodegrade in about a year (not including the ink cartridge). Filled with black ink, these smooth-rolling beauties come 12 to a pack in a variety of colors. $23.76.
