Thermoplastic elastomer (TPE) big-bust sex dolls are popular due to their affordability and soft, realistic feel. One of their main advantages is the tactile sensation; TPE is incredibly soft and flexible, mimicking human skin more closely than some other materials. This makes for a highly realistic and comfortable experience. TPE dolls are also lightweight and easier to move or reposition, which enhances usability. Additionally, their lower cost makes them accessible to a broader audience seeking quality without a high price tag. However, TPE has some drawbacks. It is porous, meaning it can absorb liquids, making cleaning and maintenance more challenging and increasing the risk of bacteria buildup if not properly cared for. TPE is also less durable than silicone; it may tear or develop cracks over time, especially with rough handling. The material can also be prone to staining and discoloration from exposure to oils, dyes, or certain cleaning products. Overall, TPE big-bust sex dolls offer a realistic and affordable option, but they require diligent maintenance to ensure longevity and hygiene.
