As the founder and creator of Elite Glass, Rob Dworkin, describes this piece:

8 hole showerhead diffuser. 19mm handmade female joint with 19mm slide included. Red caps cover all glass screw openings that help in the cleaning and filling of water. The caps are 100% watertight and are customizable. They are shipped red but can be painted any color. 10″ – 11″ height and 4″ base.

Please specify when ordering what color of screw cap you would like, otherwise you will be sent the default red. Photos courtesy of Rob Dworkin (Elite Glass).
