Good to know. I suppose with small containers, it's less likely to sit long enough to get stale. If anyone's interested, I found that wrapping bottom part of the watchmaker's tin in teflon tape (or "plumber's tape", usually $1 at a hardware store) makes the seal much better. I may go that route for storage -- and since they only hold 2-3 oz each, I'd be throwing away a lot of the surplus. Which probably needs to be done anyway. Thanks, Chris. 99? You've got me beat...I just counted 75. The wife is clamouring to store them somewhere other than four cardboard boxes on the kitchen counter . The dining room isn't a bad idea, actually...I may be able to free up some space in there.
