Many might question the convenience of having a bulletproof insert because it might be too bulky or ineffective. However, the shields are the size of a folder and can very well block out handguns and pistols. In addition to this, the bulletproof inserts come in a variety of shapes and sizes. If you find that you don’t always have your backpack around you, you can add the inserts to your purse, or the object of your liking. You can visit the websites listed on the “Where to get it” page to see what fits just right for you. The inserts have been put to the test and succeeded in blocking out pistol and small handgun bullets, though not the more powerful ones.
