Man, that does hurt. Feel better soon!

It is the 9th one down and I have only seen or bought them in yellow. They are great for crashes, (I've had a few) and the fingerless thing allows you to work with out taking them off. Very, very worth the 10 bucks!
Glad your not hurt worse. Though mega scraped up hands is no fun.
