These pieces are the same size as the more common black pieces that are commonly used in many K'NEX Roller Coasters and other sets, as well as the "Hand" pieces on the robot action figures.  Very good clean condition.  You will receive 100+ connectors with each lot purchase.  Please note that this shade is not the same as the other lighter lime green rare pieces that we have available, nor the fluorescent green 7.5" flexible rods and cross tie connectors from the Screamin Serpent roller coaster.  These pieces are a brighter green shade (matching the 2.25" rods that we also have), shown in the photos with those other pieces for comparison (other pieces not included).

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!
