"I just asked Kroy what can we do as parents to protect our children everyday in this crazy sad world," she captioned a screenshot of a bulletproof backpack on Amazon. "He said, 'Best thing we could do for now is get bullet proof book bags' you know I just did!" 

"It's better than not having anything at all," she continued. "Just thought I would share with you guys. I just found this first on Amazon so I bought it. It's certified."

Zolciak-Biermann purchased an unknown number of the "Guard Dog Security ProShield 2 Bulletproof Backpack" from Amazon, which costs $144 and is currently out of stock.

Kim and Kroy are parents to Jagger, 6, Kash, 5, and twins Kaia and Kane, 4. Kim also has daughters Brielle, 20, and Adriana, 16, from a previous relationship.
