Story highlights A Miami school is selling bulletproof panels that can be inserted into backpacks

Teachers would show students how to use the backpacks to shield themselves in the event of a shooting

(CNN) A Miami private school is offering parents an unusual item for sale: bulletproof panels for their kids' backpacks.

The Florida Christian School website has a list of items available for purchase. These include winter wear, red school logo T-shirts and ballistic panels

George Gulla, dean of students and head of school security at Florida Christian School, told CNN the bulletproof panels would add "another level of protection" to students of the pre-K through grade 12 school "in the event of an active shooter."

The school has never had a shooting incident.

"The teachers are trained to instruct the students to use their backpacks as a shield to protect themselves," Gulla told CNN in an email.
