This is the tubing used in the Classic Roller Coaster set 63030, as well as the Big Ball Factory and Hyperspace Training Tower. A single quantity of this listing is more than enough tubing for use in the complete Big Ball Factory (that set uses less than 12 total feet- two pieces, approx. 5'-8" each). The loop version of the roller coaster requires two pieces of tubing, each approximately 25.5' in length. Two quantities of this listing would be enough tubing for the complete roller coaster.
Each piece of tubing includes two orange track splice clips.
This is not compatible with the larger tubing used on sets such as the Screamin' Serpent, Rippin Rocket, or Storm Mountain that use the cross-tie type connectors to attach the tubing. This tubing attaches to the orange 5 position connectors with a tab sticking off of the middle of the top as used in the Classic Roller Coaster and Big Ball Factory.
Tubing is in good clean used condition. It may show some minor bends or other signs of use but has no major bends, kinks, or damage.
