Sounds like one of the jumbo tins- I thought those were dead!
~ 2.5x3.75x1 inch can, it says 'NET WT 1.76 OZ (50G)' from the packageing, is this the jumbo ones?
I'd probably pull out the ammonia. I'd rather not risk having everything in my kit contaminated if it breaks due to shifts in the weight.
Its in a flat pad like the prep swabs, I could more then likely run over it with a car and it not do much more then get the outside dirty.
