AirPOP mask case. Allows you to safely store and transport your AirPOP mask. Extremely elegant and slim - the AirPOP mask case allows for safe and discreet storage of the mask. Thanks to its compact size, it fits in a jacket or backpack pocket. The origami-inspired design of the mask allows it to be folded down to 33% of its original size, making it easy to store in a case. One mask-size case protects the mask from contamination, extending its life. The case is intended only for the AIRPOP masks from the Pocket series.
