Glass toys represent perfect germ safety and are known for their heat and cold accumulation ability. Amethyst Rain Butt Plug stands for anal plug perfection made of glass. Simple cleaning experience, any lube is compatible, can be warmed up or cooled down for more teasing plays – what else are you looking for with a plug for a prelude or sex play? This toy is also a tough thing – you can’t break it or even make it crack that easy as you can with other glass items as it is made of hardened and tempered glass fusion.
