4 3/4" heavy fancy cut glass look plastic tumbler with a plastic tube in the center, glued to a hole in the bottom of the glass. This allows you to have a colored liquid in the glass and stick a wand down thru the center and out the glass. You can push a silk clear thru with the wand, or just merely produce a a matching colored silk from the liquid. This is a vintage piece in Excellent condition.
The second one is a Klingl Okito Glass tumbler. It is fluted on the inside with a glass tube glued to the hole in the bottom, same as the above glass. This glass is rare and hard to find. The hole is smoothly cut and tube attached with an adhesive that has discolored some otherwise the glass is flawless!
