Each Sano Silk Mask pouch contains .8 oz of gel product. This is a full sized product containing enough product for one application covering the entire face and neck area. We do not recommend storing excess product from 1 pouch. This is because each pouch is sealed to be airtight to preserve the freshness of the botanical ingredients.[BR]Everything is inside the pouch -- no powders or mixes required! This is truly a 1-step facial.
