Grizzly Grip Utility Carabiners
$13.95
Carabiners are one of those things that you don't know quite why you need them, but you buy them anyway... Let me tell you, they are more useful than you think! I'm a graduate student and I use these to help carry the many things that don't fit in my bag with all my books -- lunch totes, water bottles, umbrellas, etc. can now all be attached to anything with a handle/loop. Really useful and great value at the price. The use is only for everyday stuff -- no rock climbing with these -- and the labels are clear about that.
