1. Keeps you cold
2. Keeps others cold
3. Great on hot days (my hands still get cold even if it's 100°F)
4. Bad for cold days
And finally 5. Annoy your friends with cold hands
My friend I was talking about last chapter hates it when I touch him with my cold hands. He slaps me and flinches when my hands get near him if he knows they're cold XD
