The following description was prepared by William Gross:
Such snuff boxes were used at Sabbath and festival synagogue prayers. During long hours of prayer, snuff boxes were passed around to the participants as a stimulant to maintain alertness and concentration. This example is a snuff box made by the firm of Lazarus Posen, the primary supplier of Jewish ritual objects to German Jewry in the late 19th and 20th centuries up until the Holocaust. The inscription is in Yiddish, recording the traditional greeting used upon meeting someone before and during the Sabbath. It is highly unusual to find such an object of German origin. There are obvious remains of snuff on the interior of the box.
Inscription: גוטען שבת Guten Shabbes (Good Shabbes)
