This is The Bag, as seen on stream, switches are not included.
The Bag is a frosted, ziplock bag featuring an Actual Nice Lock, and can contain a large amount of switches (factual amount untested), and is made of a thicker material than your average sandwich bag. Think gallon freezer thickness. The Actual Nice Lock may come off with excessive closure force but it's pretty easy to put back on. Not suitable to hold sharp objects.
Each bundle of The Bag comes with 15, FIFTEEN, bags. No, it is not $5 per bag that's ludicrous.
The Bag measures 5.5" x 7.5".
