Cups are metal and measure 3 1/4" high with mouth diameter of 3 1/8" and Finale is a metal cup with covering.  This reminds one of an effect called Thimble Rigging where an item moves about from cup to cup always at the control of the magician.  Included are 3 gimmick corks along with an extra gimmick for a cork and the Finale perfectly nests within a metal cup.  These are from Davenports in London and each cup has the Demon Hallmark stamp on the inside.  You will need to devise your own routine. Condition surface corrosion on the inside of the Finale cup, otherwise fine.
