Basically, they're single serve "pods" of everything from shampoo and conditioner to hair gel, face cleanser and shaving cream. Here's a video.
The shampoo and conditioner, which I tend to be very picky about, worked GREAT and there was enough in each pod to handle my longer-than-shoulder-length hair. The cleanser was gentle on my itchy, dry skin and I doubled up on the lotion to get my arms and legs covered.
TSA-approved means you'll never get caught in an airport without the proper toiletries and you'll never face a suitcase full of exploded shampoo again.
You can meet the PodFather himself here, and head to their website for some deals!
