SquarePegToys® Large Kidney SuperSoft Silicone Prostate Plug

The SquarePegToys Large Kidney SuperSoft Silicone Prostate Plug is an expanded, hands-free design engineered for experienced users seeking deep, comfortable prostate stimulation. Crafted from ultra-pliable platinum silicone, this massager adapts to body movement, allowing for discreet use while walking or stationary clenching exercises.

Designed by anal wellness experts, the Large Kidney represents an evolution of the original Kidney model, specifically scaled up to accommodate larger girths and provide a more intense stretching sensation. The device features a distinctive kidney-bean shape that tapers to a thick widest point before curving upward toward the prostate. This curvature is intentional, positioning the internal bulb to rub against the prostate gland as the user moves. The external base includes an upward-curving tab designed to tuck securely between the legs, ensuring the device stays in place during physical activity. Alternatively, users can rotate the plug 180 degrees, placing the longer end of the base between the buttocks for a configuration that reduces direct prostate focus, offering versatility in stimulation intensity.

Material quality is central to the product's functionality. Made from 100% US-sourced platinum silicone, the Large Kidney is available in SuperSoft Bronze or SuperSoft Graphite. The "SuperSoft" designation indicates a significantly lower durometer than standard silicone, resulting in a squishy, highly flexible texture that feels comfortable for extended wear. This softness allows the plug to stretch comfortably around the anal sphincter, making it ideal for users who enjoy the sensation of being "clenched around." The metallic pigment used in the Bronze and Graphite color options provides a bold, shimmery aesthetic without compromising the body-safe nature of the material. Because it is handcrafted in the USA, each unit undergoes rigorous quality control to ensure consistency in the soft-touch finish and structural integrity.

For optimal use, the Large Kidney is best suited for experienced users due to its substantial size. The maximum circumference measures approximately 7 inches, translating to a diameter of roughly 2.25 inches at its widest point. This girth requires adequate preparation and relaxation to insert comfortably. Users are advised to use a generous amount of water-based lubricant to facilitate smooth insertion. The smooth, non-porous surface of the platinum silicone makes cleaning straightforward; simply wash with mild soap and warm water before and after each use. Due to its size and soft material, care should be taken during cleaning to avoid stretching the material excessively. Storage should be in a cool, dry place, preferably in a breathable bag to protect the surface from dust and lint, which can adhere to soft silicone.

The product's design encourages body awareness and mindfulness. Whether used for hands-free prostate massage during daily activities or for focused solo play, the Large Kidney invites users to explore the connection between physical movement and internal sensation. The upward curve ensures that the prostate is consistently stimulated with every step or shift in posture. For those interested in the tactile experience, the soft, yielding nature of the silicone provides a unique sensory feedback that differs from firmer, rigid toys. This flexibility allows the device to conform to individual anatomy, reducing pressure points while maintaining effective contact with the prostate. The total length of 6.5 inches ensures that the internal bulb sits at the correct depth for prostate contact, while the base remains safely outside the body. This product is a testament to the brand's commitment to handcrafted, body-safe, and functionally advanced adult wellness tools.
