I purchased those masks a while back. They are GREAT. It's a fantastic value.http://us.memebox.com/memeshop/face-masks/hydro-collagen-mask-50-masks#.U6Q-crHb750
From what I understand, they come in one giant resealable bag, so you have to use them up sooner rather than later. I don't mind, I love making masks a part of my normal routine. Only thing I'm worried about now is the customs charges, but since my total order was only $51 hopefully it'll just go under the radar...
You can also leave the bag in the fridge if you want a cooling mask for summer.
