Whether the accessories are complete: Check whether all accessories are included, such as original wigs, clothing, and maintenance kits. If any accessories are missing, you may need to purchase them separately. Another important point is whether the used doll has been properly maintained. Check the following information: Cleaning frequency: Find out how often the previous owner cleaned it. If it is not cleaned properly, hygiene problems may occur. Storage method: The environment in which the best sex dolls are stored is also important. Check whether it is stored in a proper environment and avoid direct sunlight. Repair history: If any repairs have been made in the past, check what the repairs were and how they were made. You can determine the durability and quality by checking whether proper repairs have been made.
