It appears to be an old set.
I'll try to note what I can...
- The carry case stitching has come partly undone... The case does snap closed but if you really want it to hold everything in, you'll need to fix the stitching.
- aside from the 2 metal shot glasses and corkscrew, I assume the other two pieces are meant to connect to form a cup or chalice... they fit together as you can see.
