Ringless Head-Enclosing ABS Chastity Lock with Silicone Studs & Urethral Insert – D35

The D35 ringless head-enclosing chastity lock combines a compact ABS shell with built-in silicone studs, a key-operated closure and a removable silicone urethral insert. Its rounded design encloses the glans without a traditional ring around the testicles, offering a lightweight, low-profile alternative to a full-length cage. Choose Small, Medium or Large in black or pink.

Compact Ringless Design

A size-matched rear retaining ring supports the head-enclosing shell without a conventional ball-ring assembly. The compact shape reduces bulk, while the smooth, rounded exterior offers a discreet profile under clothing.

Easy Fitting and Comfortable Wear

The D35 has been tested for easy fitting and comfortable extended wear without irritation when correctly sized and used as directed. Its lightweight ABS construction, ventilation openings and spacing around the shell help support airflow and everyday comfort.

Built-in soft silicone studs provide contact points that help stabilize the shell. Select the size that fits comfortably without excessive pressure.

D35 Sizes and Measurements

All measurements below are in millimetres and apply to both colors. Overall span is the external side-view measurement including the retaining ring, not internal usable length. The rear ring fits around the shaft behind the head rather than around the testicles.

The front opening dimensions describe the aperture only, not the internal width or height of the enclosed shell. Compare the retaining ring diameter and the overall shape before selecting your size.

Removable Silicone Urethral Insert

The set includes one removable silicone urethral insert in the matching color. Its diagram gives a 47 mm overall height, a marked 9 mm shaft width and a 22.5 × 29.7 mm base. The 47 mm figure includes the base and is not an insertion-depth measurement.

The insert requires its own fit and care checks. Follow the supplied accessory instructions, do not force it into position and stop use if discomfort develops.

Metal Lock and Plastic Lock Options

Each set includes a metal lock core with two keys and four plastic lock sets. The compact key-operated closure locks the shell and retaining-ring assembly, and the key can be removed in the locked position. Follow the fitting guide for alignment and closure, and keep the unlocking key readily accessible.

IPX7 Waterproof and Easy to Clean

The D35 set is IPX7 waterproof, including the ABS body, metal lock core and supplied accessories. Its smooth exterior and removable components make routine cleaning straightforward. Clean the contact surfaces regularly, rinse thoroughly and dry the body, retaining ring, insert and lock completely before storage.
