Nothing quite like a new pinball, over time balls get damaged and this can in turn damage the playfield, tumbling is good but not as good as a set of new balls, treat your machine a least once a year.
Standard size (1 and 1/16 inches) and weight (2 and 7/8 ounces).
Pinballs are carbon-core and work great in games without magnets !
Please not these are from a new supplier so only work in games without Magnets they must have a higher content of steel than the previous supply
I now have a small supply of std pinballs that will work with magnets , shipped from USA so dearer than the UK sourced balls.
