X-MEN PRO (Stern) Plastic shield set
Stern X-MEN PRO pinball machine 15 piece set of clear playfield plastic shields. (All protectors are clear, image is tinted for contrast.)
Plastic protectors mount beneath flat artwork plastics and protrude about 1/8 inch around the perimeter of each plastic piece.
They're made from impact resistant PETG ((Polyethylene Terephtalate Glycol-modified) plastic to prevent ball damage to artwork plastics. Thin enough to mount with existing fasteners, they are also clear and cosmetically unobtrusive.
