[Re-Trinketing... Is it wrong?]

Traded for an iPod today.. and I have no use for it, although someone else might. I want to start a Geocache, and put that in there, but is it improper? Am I allowed to use something I traded for in my own GC? Or should I not even consider putting it in my GC?

[Best Geocache Containers You Can Find Around the House?]

OK, I desparately want to hide a Geocache, but before I spend ANY money on a container that's going to be open to the elements, I want to make sure that there are no household items that could be used. What should I use? Any size is OK.

 

P.S.~ I was considering using a fairly large plastic pretzel container... would that be a bad idea since it's plastic???
