One of the slimmer ones in this group: 32 mm at the top, 45 at the bottom. 185 mm tall, 150 mm insertable, on a 90 mm base that gives it a stable footing. Silicone. The narrow diameters make it a reasonable starting point at this kind of length.
Silicone wants water-based lubricant; anything silicone-based will dull the surface over time.
Wash the silicone with a mild unscented soap and let it dry completely before storage.
