Reusable, yes. Durable, probably not. Worth a shot, but I wouldn't go buying 100 of them until you try it. The reviewers on the site say the carts taste like ****, so what you'd be buying would be the atty, a USB charger and a cheap battery. There's no mention of the case being a PCC, so it's probably just a cardboard lookalike. I could be wrong, please post if I am, good luck
