Product Overview

The Silk Medium in Onyx delivers a smooth, approachable experience in body-safe platinum-cured silicone. At 5.25 inches total length with a 1.1-inch diameter, this dildo offers moderate proportions that work for users seeking something between beginner-friendly and more substantial. The deep black finish provides a sleek, minimalist aesthetic that integrates into any collection without drawing attention.

Material and Construction

Tantus manufactures this dildo using their proprietary platinum-cured silicone formula, a non-porous material that resists bacteria and is free from phthalates, latex, and other potentially irritating compounds. The silicone has a matte surface texture that reduces drag during use and creates a velvety feel against skin. This material maintains its integrity through repeated cleaning, including boiling and dishwasher sterilization, without degrading or losing shape.

The firmness sits in the medium range—offering enough structure for controlled insertion while retaining sufficient flexibility to move with the body. This balance makes the Silk Medium functional for both internal stimulation and strap-on play where some give in the material improves comfort during partnered use.

Design and Functionality

The shaft features a gently tapered head that measures slightly wider than the body, providing a defined entry point without sharp transitions. The smooth, uniform diameter along the length creates consistent stimulation without pronounced texture or anatomical detail. This neutral design prioritizes comfort and versatility over specific anatomical mimicry.

The flared suction cup base serves multiple purposes: it provides stability for hands-free use on smooth surfaces, ensures safe anal play by preventing over-insertion, and allows compatibility with most standard O-ring harnesses. The base diameter creates a secure anchor point while keeping the overall profile compact.

Care and Maintenance

Platinum-cured silicone tolerates aggressive cleaning methods. You can boil the Silk Medium for 3-5 minutes, run it through a dishwasher cycle (top rack, no detergent), or wash with antibacterial soap and hot water. This material is non-porous, meaning it won't harbor bacteria in surface cracks or pores. Between uses, store separately from other silicone toys to prevent potential surface reactions. Use only water-based lubricants with this product—silicone-based lubricants may compromise the material integrity.

Recommended Use

The 1.1-inch diameter makes this dildo suitable for users with some experience or those ready to move beyond slim beginner options. The 4.5 inches of insertable length provides enough depth for satisfying penetration without excessive reach. The firm-yet-flexible construction works equally well for vaginal or anal use (always use additional lubricant for anal play). The harness-compatible base integrates into strap-on systems for partnered scenarios, and the suction cup function allows solo hands-free positioning on bathroom tiles, shower walls, or other non-porous flat surfaces.
