Removable Weighted-Core Anal Plug with Self-Leveling Crescent Base

A removable internal core changes one broad-base plug

This weighted-core anal plug concept combines a smooth deep-plum tapered body and narrow neck with an exceptionally wide charcoal crescent base. A short removable cylindrical core loads through an underside service cavity and is closed by an indexed cap; the base is proposed to pivot slightly for external self-leveling.

The non-powered design has no vibration or remote controls. Its critical qualification points are base retention, core security, pivot control and service-cavity hygiene.

Inventory the body, core, cap and hidden pivot parts

Confirm the one-piece contact body and crescent base, removable core and matching cap before use. Ask the supplier to disclose any hidden axle, bearing, bushing, stop, spring, magnet, seal, reinforcement or adhesive inside the base.

An unmatched core or cap revision must not be substituted.

Measure insertable geometry and the external safety base

Record total body length, maximum diameter, tip radius, taper angle, neck diameter, neck length and proposed insertable boundary. Measure base span, depth, thickness, end radii and minimum distance from the neck centerline to every outer edge.

The base must remain clearly wider than the maximum insertable diameter in every relevant direction.

Document the removable core as a separate load

Measure core length, diameter, end radius, groove depth, material composition and mass on a calibrated scale. Confirm whether the plug may be used without the core and whether any other factory-approved core exists.

No improvised weight, stacked insert or third-party cylinder belongs in the cavity.

Map cavity seating and cap engagement

With all parts clean and dry, insert the core only to its measured stop, align the cap dot and rotate through the documented lock path. Record seating depth, rotation angle, engagement torque, final dot position and cap-to-base flushness.

Friction, color alignment or a shallow press fit is not evidence of a locked service cap.

Challenge core and cap retention outside the body

Mount the complete product on a padded fixture and apply controlled shake, axial pull, twist and base-flex tests below written supplier limits. Listen for core movement and recheck cap rotation, lift and cavity damage.

Any looseness, rattle, migration or tool-dependent release fails qualification.

Define the self-leveling base pivot range

Measure the crescent base angle at neutral and both mechanical stops while the insertable body remains fixed on a fixture. Record actuation force, lateral play, rebound and whether the pivot exposes a gap or hard edge.

The base should move only within a verified external range; it is not a free-spinning joint.

Test base retention under asymmetric loading

Apply low controlled loads at the center and both rounded ends of the crescent. Watch for folding, neck stretch, pivot skew, cap exposure and reduction of the effective external span.

A base that rolls edge-first, deforms around the body or hides the service cap cannot be approved.

Compare balance with and without the core

On a soft calibrated support, record center of gravity, resting angle and base contact area in both approved configurations. Repeat after pivot cycling and a timed hold.

The added mass must not pull the body away from the neck axis or make the crescent unstable.

Begin with the lowest verified mass configuration

If the supplier expressly approves unweighted use, evaluate that arrangement first with abundant compatible lubricant and full control of the external base. Add the confirmed core only after dimensions, cap retention and comfort have been established.

Heavier sensation is not a safety or performance benefit and should never override comfort.

Keep the entire crescent and service cap external

The full charcoal base, pivot and cap stay outside the body at all times. Stop for pain, bleeding, numbness, unusual pressure, loss of base control, cap movement, unexpected pivoting or difficult removal.

If the product or a component becomes retained, do not use tools; seek prompt qualified medical help.

Change the core only after complete removal

Remove the whole product, clean and dry the underside, then unlock the cap on a stable surface. Never open the cavity, test the core or change mass while the plug is inserted.

Keep the small core and cap away from children, pets and any situation where they could be swallowed or lost.

Verify all contact and internal materials

Request composition for the body surface, base, pivot, core, cap, pigments, bushings, seals, reinforcements and adhesives. Review hardness, porosity, corrosion resistance, restricted-substance and skin-contact evidence for the exact revision.

Lubricant, cleaner and barrier compatibility remain pending and cannot be inferred from the matte appearance.

Clean the cavity as a separate moisture trap

Disassemble only after removal and follow confirmed mild-cleaning instructions. Wash approved contact surfaces, then use a soft swab around the cap thread or key, cavity floor, core grooves and pivot recess without forcing debris deeper.

Dry every part completely before assembly; no boiling, dishwasher, bleach, alcohol or abrasive cleaning is approved without exact evidence.

Price the serviceable design above a fixed heavy plug

An Alibaba showroom lists a conventional heavy locking anal plug at USD 2.00-2.50 with a 50-piece minimum. It is a category benchmark only and does not establish this removable-core crescent-base design, a legal supplier or a production quotation.

The procurement reference supports an EUR 29.99 planning price after allowing for China-origin freight, exact-model quotation, insertable and base measurement, core mass verification, cap engagement and retention, pivot-range and asymmetric-load testing, balance comparison, materials, corrosion, compatibility and cavity-cleaning review, protective packing and discreet fulfillment. Packed size, weight, freight, duty, tax, insurance, payment fees and destination terms require confirmation.

Frequently asked questions

Is the weight core optional?

Only if the exact supplier documentation approves both configurations and the empty cavity closes securely.

Can another object be placed in the cavity?

No. Use only the measured factory-matched core supplied for the verified production revision.

Does the crescent base rotate freely?

No. The concept proposes a limited self-leveling pivot with defined mechanical stops, not unrestricted rotation.

Can the core be changed during use?

No. Remove the complete product before opening, cleaning or servicing the underside cavity.

How is the cap checked?

Confirm measured seating, rotation to the positive lock position, flushness and retention while the product is outside the body.

Which faults require retirement?

A loose core, moving cap, cracked cavity, corroded weight, exposed pivot edge, reduced base span, neck damage, sticky surface or trapped residue.
