per Fred Newman,

"This used BTZS Film Tube Kit is complete and in excellent condition. Tubes
have the older Darkroom Innovations name but are the same as new tubes. Here
is the product description from the View Camera Store Website.
BTZS Film Tubes are legendary among large format photographers. Film Tubes
are a simple to use rotary processing system that works better because of
random two-axis manual rotation not found in any other processing system.
The tubes not only spin but wobble in the water bath therefore agitation is
truly random.

Now you can mix different films, developers with different processing times
and run them all in one run using a minimum amount of developer - only two
ounces per 4x5 sheet - for greater economy."
