What are these called???

I bought a few of these at a pen show years ago. They can twist telescope to fit a longer pen. I need more and can't find them anywhere. Does anyone know what they are called or where to find them?

Novel way to recycle the endmill and other bit holders that accumulate in a machine shop.

I save those. I always have a need to store something.

PSI has two versions of these - both have a square cross-section, 5/8 x 6" and 3/4 x 6". They call them 'display tubes'.

Amazon has versions in a variety of dimensions
