I suppose it's necessary to avoid getting bacteria all over your light sabre.
Honestly, though, what is the market for this? Is there a person out there who is choosing their hand sanitizer based on how it relates to pop culture? (Right next to this one, not pictured, was an Avengers hand sanitizer. So there's finally something Avengers-related that's less helpful in a fight than Black Widow.)
