How real do the breasts feel on a RealDoll?

We use a special formulation of siliconee which has a gelatinous consistency. This special siliconee gel is used inside the RealDoll breasts to make them look, feel, and bounce like real breasts. The siliconee gel is cured siliconee rubber and is completely dry; it is not a liquid so a RealDoll’s breasts cannot leak. Typically the breasts will be a little firm when your doll arrives but they will soften with time.
