A 1.75 ounce chunk of Raw Kelpmineral clay (not ground) tucked into an organic cloth bag. Wet the bag and use to apply clay to your face and neck. Can also be used in the bath. It doesn't look too pretty when it is wet (hence the name "dirt bag") and can leave traces of clay (like a ring) in the bath if you add too much. No worries, use a wash cloth to clean off any clay off the bath when you drain the tub. Can be used several times. I store mine in a small ceramic bowl in between uses. It won't "go bad" just re-wet to use again. Sounds like a lot of work? It is worth it. You'll see.
