Safety is a difficult item to find on a school supply list, but one Oklahoma company is making it easier with a bullet proof backpack.

We've ran stories on these plates but we want to know how parents and grandparents feel about sending kids to school with armor intended for police officers. News 9 introduced you to Purcell Resident and Armor Advantage Owner Michael Blackmore a few months ago.

Blackmore said his product has the potential to save lives using lightweight military grade A-6000 ballistic steel.

When News 9 showed parents and grandparents video of the plates in action, their attitude went from unsure to understanding.

"It really is a shame it's gotten to this point you don't know what to expect anymore," said Larry Stacy, OKC resident. 

Blackmore sells his protective plates for as cheap as $29.

We did a quick online search and similar products sell for $60 to over $100.
