The essentials
Silexd Model 1: what you need to know before you buy
Is it for you?
Who the Silexd Model 1 is for, and who it isn't
It suits you if…
- You want a realistic dildo that changes firmness depending on whether you cool or warm it.
- You're looking for a soft outer layer with a firm core.
- You like the idea of defined veins along the shaft.
- You want to use it in the shower or bath, or pair it with a silicone torso.
Better look elsewhere if…
- You prefer something slimmer than 3.8 cm in diameter.
- You want more than 13 cm of insertable length.
- You want a design that isn't realistic, as this one reproduces the look of a penis with veins.

Step by step
How to use the Silexd Model 1
- Cool it if you want a firmer feel.
- Warm it if you prefer a softer texture.
- Use water-based lubricant. Silicone-based ones can damage the silicone surface.
- Insert it slowly and stop if you feel pain.
Cleaning
We have no confirmed cleaning instructions from the manufacturer. Here is how we would do it. Wash it before and after every use with warm water and mild soap or a toy cleaner. Then rinse it well and let it air dry. Do not boil it or put it in the dishwasher. Store it clean and dry, away from sunlight and heat, and separate from other toys.
Our tips
- Using a water-based lubricant is the general rule for silicone toys, not a fact about this product.
- We have not confirmed how or for how long to cool or warm it. Avoid boiling water, the microwave, direct heat and the freezer. Check the temperature on your skin before you use it.
- If you put a latex condom on it, do not use oils, because they weaken latex.
- Do not move it from anal to vaginal use without washing it first.
- If you share it, wash it between one person and the next or put a new condom on it for each person.
