I have a quirky use for them.---To extend the tines in the Bosch dishwasher drawers. I first cut the tubing to 19 centimeters. Then i slide the tubing over the tines---middle drawer preferredMy particular use involves the light plastic cups (Solo) that I reuse even though they only last a few months. The dishwasher jets blow the cups around. I needed something longer to hold the cups in place. This does the job.This also works for tall beer glasses and other tall, hollow objects.The copper tubing was straight, solid, unblemished and smoothly cut at the ends Nicely packaged.
