Yes, I know... Its usually BYOB! 
But this is Bring your own Pen.
So... This was one that took me awhile that MS M put out, in her series of Things I learned while caching. Just with a different container.
This could be easy for experenced cachers, but might be really hard for ones that have not seen it. Please be gental with this one, as it is not the strongest. Take the tip off, it should come apart pretty easily from there, the back will not come off.
I hope you enjoy this one, it is out in the open, but shouldn't bother anyone.
If you need help, I'd be happy to feed you clues.
Happy Caching
