Choosing the right material for your sex doll is key to improving the overall experience, durability, and satisfaction. S-TPE is a relatively new product material on the market that has attracted a lot of attention for its potential advantages over TPE. This article draws on the real insights of a loyal collector who owns multiple dolls made of TPE, silicone, and the latest WM Doll models, which feature STPE.

This review is completely unsponsored and is based on honest feedback from a senior customer with extensive experience in the real doll field. Our mission is simple: to provide you with an unfiltered, brutally honest comparison to help you decide if STPE or TPE is the right choice for your needs.

1. Durability and Surface Resistance
Similarities: Both STPE and TPE share the common issue of surface scratches. One experienced collector noted that both materials had minor scratches upon delivery, but that this did not significantly affect the usability or appearance of the doll.

Potential Advantages of STPE:
While STPE's improved durability over TPE is unproven, it's possible that STPE could rival silicone's renowned durability. Long-term use will reveal whether it outperforms TPE, which is prone to wear over time.

Conclusion: If durability is critical, STPE may have a slight advantage, but more testing is needed to confirm its superiority.

2. Softness: Full Body and Specific Areas
Body Softness: TPE is widely praised for its overall body softness, and is generally softer than traditional silicone, but STPE is softer.

For those accustomed to silicone dolls, whose breasts and buttocks are softer than other parts of the body, STPE may not be as comfortable to the touch because the entire body is soft.

Breasts: STPE's breasts are described as soft, but the feel is not outstanding. Users accustomed to high-quality silicone may find them less comfortable to use. In contrast, silicone generally offers better breast softness, especially brands such as Irontech Doll.

STPE's breast softness varies by manufacturer.

Conclusion: For those seeking the softest tactile experience, TPE still holds the edge. However, STPE offers a similar full-body experience.

3. Smell: A Major Improvement

One of the most notable drawbacks of TPE dolls is the unpleasant odor. STPE has made significant progress in this regard, with a faint, neutral odor that is neither smelly nor unpleasant. For those who are sensitive to strong odors, STPE is a game-changer.

Conclusion: For those who prioritize minimal or no odor, STPE is the clear winner.

4. Long-term durability
While TPE is known for its moderate durability, STPE is advertised as an improvement. However, long-term testing is needed to verify the claim that STPE approaches the durability of silicone dolls. Early impressions suggest a slight improvement, but the conclusion is not yet determined.
