Thanks for the information Dalin...all interesting! Until you mentioned it, I had absolutely no idea the lenses were plastic. They are very well made! These are set up kind of unique, whoever did them restored the inside just as nice as the outside, but they made the lock mechanism in such a way that you can open it carefully with a small flat screwdriver. Or perhaps I'm better at picking locks than I know smile

Wouldn't make very good piggy banks in my house Nicole, the kids would figure out a way to get in them before I could smile
