Product review (5 stars): Mancave refrigerator/freezer secure!
The only items allowed in my mancave refrigerator/freezer are pizza, ice, ice cream, bratwurst, and the occasional soda.

These ensure that only I have access.

The large adhesive pads stick solidly to the smooth, clean surface of the doors. Not exactly the best looking solution, but hey... "mancave", and with these in place, my wife and teenager cannot fill up my space with non-mancave related "overflow".
