The Castalia is a rabbit vibrator made of soft silicone and ABS, with a shiny metallic look base. The smooth shaft has a curved shape and stimulating nubs on the top, like a soft brush, which is great for G-spot stimulation. The clitoris vibrator also has these soft brush-like stimulating nubs. A special feature of the Castalia is Dual Density, which means that the core is hard and the outside of the vibrator is softer. This makes the toy feel like it’s the real thing. Another special and useful feature is the heating function in the top of the Castalia, which will bring it to body temperature for a pleasant experience during use. The 2 powerful motors are located in the top of the shaft and in the rabbit. They offer 3 levels of steady vibration and 9 different rhythms.
