Custom size sex dolls can be an exciting addition to a collection, but there are hidden costs to plan for beyond the initial purchase price. First, consider ongoing maintenance. High-quality cleaners, protective coatings, and appropriate lubricants are essential for longevity and hygiene; these items add up over time. Regular professional inspections or tune-ups to check joint integrity, poseability, and skin condition can incur additional expenses, especially if replacements or repairs are needed. Storage is another factor; safe, space-efficient stands, protective covers, and climate-controlled environments help preserve materials but require investment. Wardrobe and accessory costs can be surprisingly substantial: multiple outfits, wigs, prosthetic enhancements, and display props all accumulate, particularly for collectors who enjoy frequent refreshes or themed setups. Material degradation is a long-term consideration; silicone and certain polymer blends may require occasional refurbishment or reconditioning as the doll ages, which can involve specialized services. Shipping and insurance for delicate, high-value items are non-trivial, especially for international purchases or frequent updates. Finally, plan for downtime costs—if a doll is temporarily out of commission for repairs or cleaning, you may forfeit display or use time. By budgeting for maintenance, storage, accessories, and potential repairs, you reduce surprises and keep the collection thriving.
