This is a stainless steel / brushed nickel rainbow soap pump used to make your own soap dispenser. The thread is 28/400 which fits MOST standard soap pumps. When ordering you will need to choose whether you need the adapter to screw it onto an item or not.
Comes with 9" tube that can be cut to size using scissors.
I cannot be held responsible if this does not fit what you are wanting to put it on.
