I have seen people refer to them as coffins. That one looks nicer than others I have seen.

 

I got a couple of them years ago on Ebay... not sure what the current prices are.

I have a couple of these and like them. I have my own egg crate foam that I use in them

 

I pretty much use them exclusively for shipping watches.

 

I got a set of these following, I think I recall, your recommendation and link.

They're really good for packing in a travel suitcase or popping in the post (inside an envelope) to send the watch away for service.
