So, it's up to you whether you want a go, it's not compulsory but it's there if you want it !
You are allowed access to the cache so don't worry about that.
As you may have noticed this is a large cache so most massive TBs or swaps will fit in here.
Just a polite note - please, if you wish to take items could you do this as a trade. We filled the cache with quite a few items (some of worth) when we placed it and now it is almost empty, thank you
