【New, Unused】 Demon Slayer Disposable Masks for Children - 48 pieces Chip and Dale Individually Wrapped Disposable Masks - 10 pieces Reusable Mask - 1 piece Thank you for viewing. How about for prevention? Please check the size in the photos. I used 2 of the Demon Slayer masks. I am organizing my belongings at home and have no plans to use these, so I am selling them. Thank you for your consideration. I strive for prompt responses, anonymous shipping, and careful packaging.
