I suppose this is technically a clothing accessory, but because of the nature of Larami's products, it might also be labeled a toy.
About Larami Corporation:
Larami Corporation was a company best known in the '70s for making low-cost "rack toys" -- toys designed for checkout line type displays. In the '80s they became better known for water guns, introducing the Power Drencher, which became the Super Soaker in 1991, a line still produced by Hasbro, which acquired Larami in the '90s. The company name was retired in 2002. They made toys for many TV series and movies.
