You are looking for a small "sandwich" sized Lock&Lock
container, painted camo. It is well hidden to, hopefully, prevent
it being found by accident.
There are some small cliffs nearby and in places, some broken
glass, so this probably is not a good one for small children or
pets.
This is a small cache. Please leave "small" and take "large".
Please make sure that the lid is on securely and seals well.
If you think about it, bring a CITO bag.
