Unique Cache Container for Geocaching Hide

Description

I picked up these drain covers a while back at a thrift shop because... reasons (I'm sure there was a reason at the time)
The drain opening is heavy, over 6lbs, so it should be stable and last a long time outside.  It's
not
waterproof and does
not
have a bottom, so you should plan to provide your own internal container - this could be a hide-a-key, a jar, or such.
I think they'll make great caching hides, so I'm offering them for only plus actual shipping cost.  Limit 1 per person - let's spread them out.
