While silicone and PVC are nice, glass sex toys, such as the Fifty Shades of Grey Massage Wand and Rippled Glass Anal teaser are gaining popularity. Quality glass dildos are crafted from borosilicate glass, making them strong and chip-resistant. They last a long time, are beautiful, and easy to keep clean. They also feature fewer natural flaws than silicone or PVC and are ideal for people who want a quality dildo but are sensitive to typical sex toy materials. Glass dildos are also ideal for temperature play, able to be heated or cooled as you desire.
