Tantaly has introduced the "Grace" Heart-Shaped Ass Sex Doll, featuring a heart-shaped buttocks design and hyper-realistic skin. The product incorporates Tantabutt S, an upgraded soft-butt technology developed specifically for silicone.

Grace Doll Features and Tantabutt S Technology

The Grace doll, unveiled on September 28, 2026, features a pronounced waist-to-hip ratio and a finish with 13 layers of body painting. It is now available for purchase at Tantaly.com.

Tantabutt S powers the Grace doll, extending a soft-butt experience to medical-grade liquid silicone. This technology aims for natural rebound and realistic buttocks touch while maintaining the durability and long-term stability associated with silicone products. A Tantaly representative stated that Tantabutt S was developed specifically for silicone, allowing silicone dolls to deliver the natural rebound and lifelike touch characteristic of Tantabutt. The representative also noted that Grace continues this philosophy, aiming for users to experience the same realistic, natural buttocks touch across all materials.

The proprietary Tantabutt technology was originally developed in response to consumer demand for softer buttocks. According to the company's technical data, traditional solid buttocks are firm and durable but do not replicate the feel of real buttocks and offer limited performance in slapping, jiggling, and rebound. Common gel buttocks on the market are softer and bounce more pronouncedly but, being made entirely of gel, lack support and are prone to deformation.

Tantaly addressed these issues by adding a support layer over the gel material. The company conducted multiple rounds of testing on skin-layer thickness, the matching of inner gel softness, and the bonding of the two layers to balance soft touch and structural stability. Company data indicates that Tantabutt is 50 percent softer than previous designs, with production time increasing by approximately 20 percent.

Tantabutt was previously applied only to TPE products. Tantabutt S, in contrast, is developed specifically for silicone.

Grace also features a dual-channel design and an integrated skeleton-free body. This design enhances buttocks stability and provides a consistent touch while reducing maintenance requirements. Weighing approximately 23 lbs., the product is suited for long-term users who prioritize realism and durability. A Tantaly brand representative stated that softness and durability should not be a trade-off.
