This is the silver version.

It looks matt to me. But it doesn't look out of place next to the rather shiny tap.

Disassembled, the tube is 20 cm long. With a wine bottle, you have about 4 cm left measured from the bottom.

The outer diameter is 27mm, the inner diameter is 26mm and the thread pitch is approx. 5mm. The thread is not meant to be screwed directly onto the bottle but it has an attachment which can be mounted in all bottles with an inner diameter of 12mm to approx. 22mm. The dispenser can then be screwed onto this attachment.
