All ONNA glass 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.
WE ONLY WANT TOP QUALITY FOR YOUR SAFETY AND YOUR PLEASURE.
ONNA glass toys are perfectly safe, smooth, hypoallergenic, non-porous, and can be used with any type of lubricant. The smooth and hard surface of glass 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. They naturally warm up to body temperature very quickly, which feels truly fantastic.
