How do I store a silicone sex doll?

Store it either hanging upright from a proper hanging kit, or lying flat with the limbs relaxed and no weight resting on any single point. Prolonged pressure on one spot is the main cause of permanent deformation, so avoid leaving the doll seated or folded for long periods. Keep it out of direct sunlight, make sure it is completely dry before it goes away, and avoid long contact with unwashed dark fabrics — silicone resists dye transfer well, but months of contact is still months of contact.
