Our Test Tubes ...
We cut our tubes into 22 inch lengths and the tube sizes range from 18" to 28". They should fit any standard size printing pallet. There are approximately 100 tubes per 25lb box (more if the tube sizes are smaller, less if larger.) Most printers rotate the tubes so that they can get multiple prints on a single test tube and some even turn the tubes inside out effectively doubling their capacity!
Call me if you have questions!
