NOS Grace F9E question


A friend of mine gave me a Grace F9E to try on my 1200G.  He thinks it may be a good fit.  It appears to be brand new and never used.  It has a plastic protector that covers practically the entire cartridge.  I cannot get it off as it is on there very tight.  Is there any special way to get it of and not damage the cartridge?

Any suggestions would be appreciated.

Yes @tzh21y   You're thoughts on the cart? I have this cart and the Technics GR and it's wonderfulllllllllllll....
F9 is not a winner in the Grace line, it’s a good cartridge, but only a STARTER for those who’re looking for a magical Grace Sound. The best are F14 and LEVEL II series, only those top of the line models i can call the best MM. Grace has improved everything, for example the coil wires in LC-OFC versions, then gave us the best cantilevers (such as BR/Boron Pipe and BE/Beryllium) and the best styli (such as MicroRidge / MR). The F9 (designed in the 70’s) is a joke compared to the LEVEL II or F14 (designed in the 80s).

There is an interesting model between F9 and F14 and LEVEL II, this is F12 MM
