I believe there are at least 30 pieces in a bag for the cut items (there are two bags, and I think some have been used from one of them). I think I used a few of the uncut items, but I don't know how many are left. Please refrain from purchasing if you are concerned about dust or other issues due to long-term storage at home by a non-professional. The bags (especially the adhesive parts) may be dirty. As these are overseas products, there may be initial dirt, debris, or burrs. Handmade, handicrafts, DIY masks
