Popmask London

Always fun and forever beloved. Bring a night of friendship and laughter to a peaceful close with these Rose-scented Sleepover Mask. After a movie and popcorn and maybe some face masks, this is the perfect way to drift into a deep slumber together.

When the pouch is opened, the iron powder inside heat cells reacts with oxygen in the air causing it to heat up gently. The mask reaches a maximum temperature of 100.4 F or 38 C and stays at this temperature for at least 20 minutes.
