The story

The 4-inch resin cock cage from Lockmaster — slightly larger than the 3.5-inch sibling, sized for users who need a bit more length without committing to extra-large dimensions. Resin holds firmer than silicone for a more pronounced confined feel.

Four ring sizes ship with the unit so users can match the wearer's anatomy through testing rather than guessing. Practice short sessions before extending wear, especially for first-time cage users.

Hand wash with mild soap and warm water. Pair with water-based lubricant for insertion comfort. Air dry before storing.

Good for: chastity play, dom/sub scenes, multi-ring fitting, beginner-to-intermediate cage wearers, longer-length resin cages.

OUR EDITORIAL STANDARD

Body-safe materials. Brands we trust.

Questions before you buy?

Will this arrive in discreet packaging?
Yes — all orders ship in plain, unmarked boxes with no product names and no brand logos on the outside. We ship discreetly on every order, automatically.
What's your return policy?
Sex toys can't be returned once opened — that's an industry-standard hygiene rule, not specific to us. For defective or damaged items: we'll replace or refund. Email us and we'll handle it.
Is this product body-safe?
We carry only products that meet our editorial standard: body-safe materials, no phthalates, no BPA, no latex in products marketed for internal use. Our board sets the bar; this product meets it.
How do I clean it?
For non-motorized toys: warm water and mild soap, or a dedicated toy cleaner. For motorized or electronic toys: wipe with a damp cloth and toy cleaner — don't submerge unless the product is rated waterproof. Waterproof rating is noted in the specs section when applicable.
Is this rechargeable?
Check the specs section on this page for charging details. Most modern vibrators and massagers include a USB-C or magnetic charger. Battery-powered products are noted clearly in the Materials & specs accordion above.
Can I order anonymously?
Yes — guest checkout is available, no account required. We ship in plain packages with no external branding. The charge on your card statement appears as "Alexander Institute" — the parent company that owns Loving Sex, nothing that identifies the product type.
