A string of three hand blown, solid glass balls in graduated sizes with a slight twist. Just like the standard anal beads, the balls are held together by an ultra hygienic silicone strap.  These balls are however equipped with soft silicone spikes on the strap for that extra bit of sensation.  The string features a removable silicone strap for thorough cleaning. Glass and silicone become slick when lubricated. Both materials are durable, non-porous, waterproof,  and phthalate free.
