Hollow Dildos

Hollow dildos are adult sex toys featuring a firm, hollow interior that fits over the penis or a prosthetic. They are used to add length, girth, or firmness during penetration. These products can also support users with partial erections, offering stability and shared sensation for both partners through a secure, structured shell.

Design and structure

A hollow dildo includes a cavity that the wearer fits into, with an external shaft that provides shape and size. Most attach to a harness or include a flared base to prevent slippage. Designs vary from open-ended for natural contact to closed-tip for firmness and full coverage, depending on comfort preference.

Material and sensation

• Firm silicone: Body-safe, durable, and easy to clean with mild flexibility for stability.
• TPE or TPR: Softer touch with mild compression, suitable for snug fits.
• ABS plastic shell: Lightweight and rigid, used in outer casings for structure.
• Cyberskin or Real-Feel blends: Provide lifelike warmth and texture while retaining firmness inside.
• PVC (phthalate-free): Maintains shape and allows visible finishes or colour variation.
• Rubber-core hybrids: Used in flexible shafts for better movement without losing pressure.

Use and fit

Apply lubricant inside and outside before use. The penis or prosthetic slides into the inner cavity until comfortably sealed. A harness keeps alignment steady. Some users select open-tip versions to retain skin contact and heat transfer. Sizes range from 12–35 cm insertable length, with various girths for secure fit.

Cleaning and hygiene

Wash thoroughly after every session with warm water and mild soap. For hollow interiors, use a narrow brush or irrigation cleaner to reach inside. Let the cavity air dry fully before storing. Keep away from direct sunlight or excess heat to preserve shape and colour. Use condoms inside for added hygiene.

Black Dildos — Black dildos include a variety of firm, body-safe designs with a sleek finish. Many hollow styles are available in black silicone or PVC for a discreet, neutral look. Dark surfaces also reduce visible wear and maintain a polished appearance over long-term use.

Pink Dildos — Pink dildos feature lighter tones that highlight contour and texture. Hollow variants in pastel or translucent pink show inner detailing and edges clearly. Colour choice is personal, and soft shades help visual tracking of movement during shared play or camera use.

Hollow dildos balance structure and sensitivity, letting both partners share movement and pressure safely. With solid shells, secure harness options, and realistic surface materials, they create a controlled, supportive experience for users who want confidence, comfort, and mutual sensation during penetration.
