When you hate someone so much you consider them an enemy you begin to consider sending them something awful, something that shows just how much you dislike that person.
But when boxes full of feces and strongly worded memos aren't enough you need something that cuts straight to the bone, like these hand painted postcards for your enemies by Killien Huynh of KAA Studio.
Killien's happily hateful postcards feature watercolor paintings of cute little critters delivering dark messages to your enemies, warming the heart of the hated before stabbing it with a snappy slogan.
