It takes a special kind of dude to design a line of underwear for women called Period Panties. These are awesome!
The creator, Anthony, has been selling them for a while, but they constantly sell out. Hence the Kickstarter campaign to expand the collection, manufactor more undies, etc. He met his $10k goal in 6 hours, and as I'm typing this, has made almost $72k.
That's a lot of Period Panties.
My favorites are the Evil Beaver and Rainbo: First Blood.
He's probably going to get sued a little bit over the Grumpy Cat knockoff, though.
