Howl’s Moving Castle Face Masks were created to commemorate the release of Studio Ghibli 's newest film, Howl's Moving Castle. They are now available in our Howl's Moving Castle Merch store. One of the most unique and iconic creations from Hayao Miyazaki’s Howl's Moving Castle is the Howl’s Moving Castle Face Masks, which were first introduced in the novel by Diana Wynne Jones, who won a Carnegie Medal for her achievement. From alluring purple-and-gold crescents to royal blue baroque bows, these face masks are creative and fun.
