Flat chested sex dolls are generally easier to manage in terms of storage, cleaning, and transportation. Their compact size makes them suitable for smaller living spaces and more discreet storage solutions. Full-bodied dolls require more room, both for storage and use, and their heavier weight can make maintenance more challenging. Buyers with limited space or those prioritizing convenience often gravitate toward flat chested models, while those seeking a more immersive and visually dramatic experience may prefer full size sex dolls.
