This binder is not actually bulletproof, but with 3/32″ aluminum sheet covers, nickel-plated steel piano hinges, and all-riveted construction, it’s a dern sight tougher than just about any other 3-ring binder you’re likely to encounter in the wild. Especially those wimpy cardboard-shrinkwrapped-in-vinyl models most of us had to make do with as schoolkids.
