This mug has 2 chambers connected with a few holes, not sure of the proper name. I have been told that in the top part you drop the tea bag and then you pour hot water that collects in the lower chamber as ready to drink tea.
Other uses have been suggested from soap older to shaving mug, but I think the tea mug is holding up the best.
The mug is in very good condition, with some wear on the gold rim, has no mark even thou we can see the impression of a number (275) on the bottom.
It is 4" high and about 3" wide
It will ship USPS Priority Mail with Insurance included
