Why choose a glass dildo? Glass behaves differently from silicone. It is completely rigid, so it gives firm, exact pressure and keeps its shape against the body. Its surface is very smooth and glides with only a little lubricant. It also holds temperature: a few minutes in warm water or in the fridge changes how it feels on the skin. The Double Crystal is made of solid borosilicate glass, a type chosen because it stands up to heat, cold and chemicals.
Satisfyer Double Crystal: two textures in solid glass
The Satisfyer Double Crystal is a double-ended dildo made from solid borosilicate glass. One shaft is smooth for an easy, gentle glide. The other is ribbed for more intense sensation. A wide handle sits in the middle, which gives you a firm grip whichever end you use and acts as a stop during anal play.
It is 7.9 inches long and weighs 14.1 ounces, so it has a satisfying heft in the hand. With no motor or battery it is silent, fully waterproof, and can be warmed or cooled before use. It also doubles as a massage tool for the body.
Best for: For anyone who prefers firm pressure and texture to vibration, and for people curious about temperature play. It can be used vaginally, including for G-spot pressure, anally, or externally for massage. It suits all genders, solo or with a partner.

How to use
Wash the dildo before first use and check that the glass has no chips or cracks. Use it at room temperature, or place it in warm water first for heat, or in the fridge for a cool feel. Test the temperature on your wrist first. Apply a little lubricant to the end you want to use and hold the wide center handle. Insert slowly. A gentle rocking motion often works better than thrusting with a rigid toy, because it presses on sensitive spots more precisely. Clean it before switching between anal and vaginal use.
Care
- A little water-based lubricant is all the smooth glass needs.
- Wash with warm water and soap, or toy cleaner, after every use.
- Warm it in warm water or cool it in the fridge. Test the temperature on your skin first.
- Inspect the glass before each use and do not use it if it is chipped or cracked.
- Store it in a padded pouch so it cannot knock against hard objects.

Frequently asked questions
Is a glass dildo safe?
The Double Crystal is solid borosilicate glass, not hollow. Satisfyer describes the material as stable and shatterproof, and resistant to heat, cold and chemicals. As with any glass toy, check it for chips or cracks before each use and stop using it if you find damage.
How do I warm or cool it?
For warmth, place it in warm water before use. For a cool sensation, put it in the fridge. The glass holds the temperature for a while. Always test it against your wrist before using it on sensitive areas.
Can I use it anally?
Yes. Satisfyer designed the wide handle in the middle as a stop for anal use, and it also gives you a firm grip. Use plenty of lubricant, go slowly, and wash the toy before moving from anal to vaginal use.
What is the difference between the two ends?
One shaft has a smooth surface, which glides easily and suits gentle massage. The other is ribbed, which adds texture and a stronger sensation. You can switch ends at any time by turning the dildo around and holding the center handle.
Does it vibrate?
No. There is no motor, battery or charging. The sensation comes from the rigid shape, the weight, the two textures and the temperature of the glass. That also makes it completely silent and waterproof.
