It may be bearproof but I think I would be able to get through it even if you didn't give me a key or combo. Seriously if you try Entenmann's Star Puff's they are better than KK. and they stay good for 5 days compared to 12 hrs for KK. They aren't in every market yet, so you'd have to check the stores in your area. Not trying to put out an advertisement here. Just trying to help everyone get a little fatter.
