These free bio golf tees are basically just like normal golf tees with the added bonus that they're good for the environment. When they break and get left behind on the course, they'll eventually break down and not release any toxins into the environment.
I'm not sure when I'll ever use these, but I can always stick them in my dad's bag. I don't golf that much, I just like driving the cart around and drinking beer with my buddies while screaming “FORE!!” If there was some way to score that, I'd make the equivalent of a hole-in-one every time and be just as famous as Tiger Woods.
