I really appreciate the ingenuity of this set. Made in the 1930's, the cup consists of three metal rings that are graduated in size to expand and collapse when needed. The cup also has very beautiful detailed etching, & measures 2 3/4" tall when expanded. The thick leather case could easily fit in a pocket. In great condition considering it's age. The largest ring on the cup is very loose and doesn't stay in place very well. And the leather case shows some wear but is still incredibly thick and sturdy. Price is for the set.
