There's nothing worse than coming up after an exhausting day battling the forces of evil only to discover you can't get to sleep. If counting Pokémon doesn't do the trick, you may want to try one of these superhero sleep masks.

Sold by Shuba Gift Factory, each of the three masks in the "Heroes Never Sleeps!" series features a cartoonish depiction of a different superhero fighting slumber: Batman (complete with Bat-ears), who uses matchsticks to keep his eyes open; Spider-Man, who draws alert eyes on Post-It notes; and the Incredible Hulk, who resorts to tape.

They're available for $15 each, or the set of three for $47.
