Costco Masks - 30 Pieces - Gokujo Space Size: 175mm x 95mm I found these at Costco by chance and bought them without thinking, but I have others, and the total number of masks isn't decreasing, so I thought I'd give away the individually wrapped ones to someone. Perfect for those who want to try them out, or for those who prefer the convenience of individual packaging! The individually wrapped masks will be sent in a clear bag. Shipped via anonymous delivery. Costco Masks Gokujo Space Regular Size Standard Size Individually Wrapped Nose Wire Center Wire Hay Fever Cold Prevention
