Compared to standard torso sex dolls, granny sex dolls require more frequent skin care, especially since the specialized materials used to simulate aging skin can show signs of wear more easily. Regularly inspect the internal skeleton structure and tighten any loose parts. When not in use for extended periods, professional storage measures should be implemented, including temperature and humidity control in the storage environment and the use of support frames to prevent deformation. This maintenance system ensures the product remains in optimal condition.
