POPBAND Popmask Scented Self Heating Eye Mask for Sleeping - Warms In 20 Seconds, Natural Heat Source, Lasts For 20 Minutes - Pack of 5 CHAMOMILE Cotton Eye Masks With Ear Loops, Multicoloured

Our Popmask Calm Self Warming Eye Masks are infused with chamomile to provide aromatherapy and help soothe weary eyes with gentle warmth and calming steam so you fall asleep comfortably. The eye mask is made from non-woven cotton. Each heat cell contains iron powder, vermiculite, activated carbon, salt, and water, which are all naturally occurring ingredients. The mask is free from artificial ingredients. 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 degrees Fahrenheit and stays at this temperature for at least 20 minutes.
