I've used about 5 sheets. When taking them out, I used the included tweezers, so I haven't touched them with my hands (disinfected). The contents are soaked in liquid and are in usable condition. I don't remember when I bought them. Please refrain from purchasing if you are looking for new items from a store or if you are very particular, as these are stored at home by a non-professional. I am also selling other cosmetics and clothing. Please consult with me for a discount if you purchase two or more items. Brand: VT Product Name: TX Toning Daily Mask
