Just opened my first one. There are 10 tabs you need to break to open one side of the enclosure. I don't see any way of opening this without breaking tabs. The tabs are connected to the lid, and slide into a rectangle holder on the fat body, with the catch on the inside, not the outside. Can't even shim all 10 tabs to open it gracefully if you wanted to. Trying to disengage the catch on the opposing side from the inside was a failure, there's no slack/give. I don't think there's a way to non-destructively opening these.
