Very good, clean condition.  They may show some minor signs of use but are in very good condition overall.  These are the same size as the more common red and yellow balls from the Big Ball Factory.  No broken pegs.  The halves of each ball can be separated and mixed with K'nex balls of other colors if desired.  You will receive 4 complete silver balls with each lot purchase.

The colors or appearance may vary slightly.  These pieces in particular tend to show the flow paths of the plastic as it cools from a liquid to a solid during the manufacturing process (final photo shows one of the more dramatic examples).

Buy from us with confidence! I am a lifelong avid K'NEX builder.  I know the parts well and have a huge selection.  Please feel free to contact us with any questions, or if we can be of any help finding a specific part for you.  I would be happy to put together bulk lots of any part and quantity that we have available.  Thanks for looking!
