Starpery Fourth Generation Weight Reduction Technology

Hold her in your arms—and discover a new definition of lightness.

What you feel is no longer weight, but perfect balance, deep softness, and a level of realism that redefines modern sex dolls.

With the debut of Starpery WR4.0, we elevate intimacy through precision engineering—where innovation, comfort, and realism exist in complete harmony.

Dual-Mold Foaming Technology-Engineered Lightness, Designed Softness

At the core of WR4.0 lies our advanced Dual-Mold Foaming Technology. By bonding the outer body mold and inner core mold directly to the skeleton during production, we create an ultra-soft, lightweight foamed structure from the inside out.

Every layer is carefully calibrated. Foam thickness is precisely controlled to enhance lightness without sacrificing strength, resulting in a body that feels airy yet stable, soft yet supportive. The outcome is a sex doll that is effortless to lift, hold, and embrace—while remaining structurally reliable and lifelike.

Flow Groove Technology-The Secret Behind Seamless, All-Body Softness

Reducing weight often compromises feel—but not with WR4.0.

Our proprietary Flow Groove Technology uses meticulously engineered channels to regulate the flow, speed, and volume of liquid silicone during foaming. This prevents inner core compression and completely eliminates unwanted silicone infiltration.

The result is consistent softness from surface to core. The body moves naturally, yields gently under pressure, and maintains long-term durability—delivering a tactile experience that feels authentically human.

From WR3.0 to WR4.0-A True Leap Forward in Sex Doll Realism

Compared to the 3.0 generation, WR4.0 sex dolls are significantly lighter while preserving natural curves and realistic body fullness. Softness is no longer limited to the surface.

In earlier designs, areas such as thighs and internal sections often hid rigid, stone-like cores. With WR4.0, softness extends throughout the entire body—fully integrated, uninterrupted, and naturally responsive.

This is the real breakthrough:

You can now hold her in your arms with ease. No strain. No heaviness. Just natural closeness.

Intimacy Without Weight-With WR4.0, every embrace feels effortless.

• The body feels alive.
• The softness is genuine.
• The lightness transforms the entire experience.

Starpery’s Lightweight Technology is more than an engineering achievement—it is the evolution of premium sex dolls. The freedom to experience realism without burden. The art of intimacy, perfected.
