Keeping these pen cap utensils on-hand is a great way to simplify the eating experience when you're out and about. Instead of needing to carry both a pen and disposable utensils, these nifty little add-ons can make a fork, spoon or knife out of whatever writing utensils are kicking around in your car or purse.
Plastic utensils account for significant waste in landfills, so taking away much of the added material and replacing it with a reusable item is a fantastic solution to an unknown problem. They're also a great thing to keep hanging around your desk for easily transforming a pen into fork when the crunch is on and taking a full lunch isn't conducive.
With all that said, the pen cap utensils still leave you eating with a pen, so they are a tad goofy.
