GLASS PLEASURE WANDS All ONNA glass sex toys and glass pleasure wands are hand-blown premium quality glass toys made of the highest-quality medical grade borosilicate glass. They are annealed at specific temperatures and times to ensure the most durable and most stable glass, unlike other cheaper, mass-produced sex toys. Every single piece is checked under polariscope to make sure it is perfectly safe. ONNA glass pleasure wands are perfectly safe, smooth, hypoallergenic, non-porous, and can be used with any type of lubricant. The smooth and hard surface of glass dildos and glass sex toys is also excellent for internal erogenous zone stimulation, G-spot, or prostate play since a firm touch is needed to stimulate these spots. They are fantastic for temperature play when you run the wand under warm or cold water for added sensation. Glass sex toys will naturally warm up to body temperature very quickly, which feels truly fantastic. WE ONLY MAKE THE HIGHEST QUALITY GLASS PLEASURE WANDS AND GLASS SEX TOYS FOR YOUR SAFETY AND PLEASURE.
