The propellant in these spray strings is extremely flammable, creating a serious risk of burn injuries when sprayed near an open flame, such as birthday candles.
Federal law bans flammable products intended for use by children.
CPSC is aware of at least one report of a burn injury resulting from the use of these spray strings. Crazy Ribbon and Crazy String both spray strings of various colors, and come in round metal spray cans about 6.5 inches high. The cans are silver with plastic caps that match the color of the spray string. Depictions of various colored streamers cover the cans. The CPSC says consumers should stop their children from using the spray string immediately.
