The grinder these parts are from was owned by my mother and looks new.  I doubt she ever used it - but if she did it was at most a handful of times.  The only signs of possible wear that I can see are on the metal extruder parts - but - likely this is just the way they appear new as they still look much better than others I see on eBay.  

Take a good look at the photos to see the condition of the part you are interested in.

Buy more than one at a time!  

Note: if buying more than one item in the same order there is only a $1 additional charge for each additional item after the first one.
