* The new "solid tubes" are slowly going to replace the "milky" tubes on this store. I have been using these for months now, and I'm finally making them available to you. They are way brighter, and come with a blackout backing (no need for the black cover) *
Here's a long and a small tube with a provided extender. You can stack them to make them longer (up to 46.5 inches). We teach how to use these tubes on this Youtube channel and in my private learning group.
