Children's masks featuring illustrations of Pokémon characters, 30 masks per pack with a cute design. Individually packaged for easy use. The masks have a shelf life of 3 years from the date of manufacture, with an expiration date of September 18, 2025. However, as far as I have used them, there was no problem at all. As the season of infectious diseases and pollen is approaching, why not buy in bulk for prevention? - Brand: Pokémon - Model: Children's Masks - Quantity: 30 masks x 40 boxes - Design: Illustrated with Pokémon characters We are not considering selling individual packs.
