Shampoo Bottle Nozzle

A simple customizable shampoo and/or bodywash bottle nozzle I use to fill the smaller bottles in my wash bag.
It includes a groove for a 1.6 TO 2 mm diameter (1/16" TO 5/64") 'O' ring as shown in the photo to help make a seal to the bottle. It is still recommended you hold the nozzle in place when squeezing the shampoo/bodywash from the bottle,
