Nothing on this object explicitly suggests that it was intended as an etrog box: there are no Hebrew inscriptions, nor are there any images of the etrog fruit. The maker, Fraget n Plaque, made a considerable amount of Judaica (e.g. Hanukkah lamps). But many of their objects (probably most) were secular. The box is just large enough, however, to fit an etrog inside—thus making it possible to serve as an etrog box. As a result, this object may have been used as an etrog box, even if that was not its intended purpose.
