The best

I use this to document conversations and video the police

The hard shell case is very high quality and opens and closes with a zipper which I prefer. It’s very sturdy which reassures me that it will most likely protect the pen if packed in luggage or dropped. A real plus and must have with each pen. Don’t leave home without it! I like having the USB charging cord, ink refills and pen all in one small case.

It works very well but when I used it they could tell that it had a camera in the pen so it's not very discreet
