Ultra-three-dimensional mask with 99% filter function, 28 pieces. ⚠️ I purchased a pack of 30, but the size was too small for my 6th-grade child, so only 2 were used. There are 28 unused pieces remaining. Please consider this before purchasing. The zipper on the package is broken, but the bag will be folded and included. - Brand: Unicharm - Type: Mask - Quantity: 28 pieces - Features: 99% filter function - Design: Ultra-three-dimensional shape - Size: 66mm x 128mm To reduce the thickness, I will ship them as shown in the third photo.
