Christmas cards are often adorned with brightly lit trees or smiling families, but Dirty Santa holiday greeting cards feature inappropriate sketches that aren't safe for work.
Created by Justin Winslow, Dirty Santa cards are decorated with cheeky illustrations including Mr. and Mrs. Clause getting it on and others that have slogans like "Sit on Santa's lap and tell him how you like it!" Other ones feature a scantily clad Santa dancing around the North Pole as well as another that has Rudolph the reindeer getting frisky with Santa's leg.
The cards come in packs of six and also feature envelopes that are adorned with the word "Naughty" on the outside to ensure that recipients know what they're in for when they open the envelope. Just make sure you don't accidentally give your mom one.
