Excellent clean condition.  These are top quality pieces that are undamaged, non-discolored, bright neon yellow in their original condition.  These translucent balls are made from a more brittle material than the standard red and yellow balls so they tend to discolor over time and get damaged more easily.  The pegs that hold the ball halves together also tend to break more easily.  This listing is for pieces with no broken pegs and no significant discoloration or damage.  They may show some light signs of use but are in excellent condition overall.  Photos show one compared to a standard red/yellow ball as well as a commonly discolored neon yellow ball.

You will receive 2 complete assembled balls with each lot.  Multiple lots available with quantity discounts.
