Definitely not disposable or a one timer. These are a S&B product after all, compatible with the Mighty, Crafty, and I do believe the Volcano has a reducer that takes the capsule too. These are pretty solid, a little tight to open at first but they get easier with use. They can be bent out of round, but easy to bend back. They don't even really get dirty. Consume, dump abv, stash till reload day.
