I’ve never worked with a “slippery” shell before. I’ve had several other types. This shell is very
nice. Now, when they say slippery…they really mean it. You have to be careful and get used to it a
bit before performing. This shell is absolutely silent, and as anyone who works with coins knows, no
talking is a major plus. Also, these are shimmed, with an edge halfway around. This is a detail I
wasn’t aware of, but is yet another advantage. Definitely recommend.
