41 Grams of Plant Resin

The store describes an all-natural plant-resin cage with an overall weight of 41 g. This is a published product figure, not a guarantee of comfortable fit or suitability for exercise. Check the material and every contact surface if you have skin sensitivities.

The open design may allow some airflow. It does not remove the need to take the device off for cleaning, skin checks and drying; do not assume it is safe for extended wear.

A Base Ring You Can Actually Put On

The clasp-style base ring opens instead of requiring the wearer to pass through a closed ring. Fasten it only when the skin is clear of the closing point, and check that it does not pinch or restrict circulation.

Original product images show three ring options, but the size charts disagree: one shows 45 / 50 / 55 mm and an older image shows 40 / 45 / 50 mm. Confirm the actual included sizes with the store.

Not Sure About Size?

Original images conflict on ring sizes. Check the current set with LOCKINK before choosing.

A Lock That's Built In, Not Bolted On

The inset mortice lock fits into the top of the cage instead of hanging from a separate loop. Its profile may be less noticeable under clothing, but silence and invisibility cannot be guaranteed.

The seller describes the lock as bronze and resistant to rust. Corrosion is still possible with moisture and body fluids. The live listing does not provide a waterproof rating, so remove the device before showering and dry the lock after cleaning.

Three Ways to Wear It

01

Your First Cage

Inspect the clasp and choose a ring that does not pinch. Practice fitting and removing the unlocked cage first, and keep the keys available to the wearer.

02

Hand Over the Keys

The original package illustration shows two keys. Keep a usable key or an independent release plan with the wearer, rather than relying entirely on another person.

03

Check Fit During Short Sessions

Start with brief, supervised wear and remove it for cleaning and regular skin checks. Do not sleep, exercise or shower while wearing it; remove it immediately if pain, numbness, swelling or discoloration occurs.

Ready When You Are

Safe Use & Care

Measure and check the actual included rings first. Never use a ring that pinches or restricts circulation. Remove the device immediately for pain, numbness, swelling, color changes or irritation; do not sleep in it or leave a wearer unattended. Keep a reliable removal key accessible.

Clean the removable surfaces according to the supplied instructions, then dry thoroughly. Keep the metal lock dry and check it for corrosion. Do not assume the device is waterproof or safe for showering.

Questions, Answered

Which ring size should I choose?

The primary original size image lists 45, 50 and 55 mm, while an older graphic lists 40, 45 and 50 mm. Ask LOCKINK which three rings are included with your chosen option; fit must not cause pinching or circulation problems.

Is this a good first cage?

The opening clasp ring may simplify fitting compared with a closed ring, but beginners should verify dimensions, practice removal, and start with short supervised sessions. Lightweight does not mean risk-free.

Can I wear it in the shower?

The seller describes a rust-resistant bronze lock, but does not give a waterproof rating. Remove the cage before showering and dry all parts after cleaning.

Will it show — or rattle — under clothing?

The lock is inset rather than dangling. Visibility and sound depend on clothing, fit and movement, so discreet wear cannot be guaranteed.
