These are silver SPINDLE SPINNER where the anodizing is a little dull and/or the discs have small cosmetic imperfections. No scratches, no real damage just a little less success in polishing the discs or anodizing the handles.
From a mechanical standpoint these will work every bit as good as regular ones.
A chance to get your SPINDLE SPINNER at a lower price. If you don't like it you can return it within a month like a regular one.
