I think this silver and glass shell compact is so unusual and rare. It is marked Star 875 and has an additional mark that I can not make out. The shell shape is pink and white glass and it is all in very good condition. The star 875 indicates it was marked after 1958 in Russia. The interior where powder would have gone has a lovely gold wash. Measurements are 2 3/4" across by 3 1/8 in height. very attractive and rare.
