According to the Jewish Virtual Library, “Our knowledge of Torah cases and mitpaḥot in pre-modern times is meager; the process whereby the case evolved from a mere receptacle for carrying the Torah into a sacred artifact can at most be conjectured.”

Here we have a sefer torah scroll within a cylindrical “tik” or case with an onion shaped crown.“Cases may be adorned with colorful drawings or covered with leather, fabric, or beaten silver plates”. This particular case is composed of silver-colored plastic and adorned with hanging baubles and red and blue tones. Torah cases come in a variety of shapes, and styles that stem from different regions of the world. The onion shaped crown stems from Babylonian communities.
