Four-Size Color-Coded T-Base Anal Training Set

Move through four clearly separated sizes

This four-size color-coded T-base anal training set concept contains exactly four progressively sized smoky-plum trainers. Each illustrated piece combines a rounded taper, narrowed neck and broad T-shaped base, while a different recessed base inlay helps distinguish its place in the sequence.

The image establishes the proposed form and count only. It does not verify measurements, materials, hardness, flexibility, colour-code meaning, lubricant compatibility, cleaning method or sale-ready production.

Audit all four pieces before packing

The planned inventory is one smallest, one small-medium, one medium-large and one largest trainer. Number them S1 through S4 from left to right and confirm that every pack contains one of each size.

Reject duplicated sizes, missing pieces, mismatched colour inlays, deformed tips, split necks, incomplete bases or surfaces with cuts, pits, seams or embedded debris.

Measure the progression rather than naming it

For S1 through S4, record total length, usable length, maximum body diameter, neck diameter, neck length, base width, base depth and mass using the same datums. Publish only approved finished measurements with tolerance.

Small, medium and large labels are comparative within this set; they do not establish suitability for an individual user.

Compare every diameter and length step

Calculate the absolute and percentage change from S1 to S2, S2 to S3 and S3 to S4 for maximum diameter and usable length. The sequence should be deliberate and free from an unexpected jump.

Exact increments remain pending physical samples. The image must not be scaled to estimate dimensions.

Inspect the rounded taper for local defects

Map the entry profile from tip to maximum diameter and check the four pieces for symmetry, sink marks, sharp ridges, flash, hard inclusions and abrupt shoulders. Measure tip radius and the distance required to reach each diameter.

A smooth-looking render does not prove production smoothness; each approved lot needs visual and tactile inspection under controlled conditions.

Characterize each narrowed neck

Measure neck flex under a bounded lateral force, recovery after release and permanent set after repeated cycles. Compare S1 through S4 because a thicker piece may not behave like the smallest piece.

Flexible, firm and soft claims remain pending a declared test method, temperature, conditioning time and acceptance limits.

Verify the T-base as a safety feature

Confirm that every base is substantially wider than the neck and cannot pass through the approved retention gauge. Record base span, edge radius, torsional stiffness, rocking and distortion under bounded load.

Do not use a piece whose base is damaged, folded, excessively flexible or able to travel beyond the external safety boundary.

Use the four inlays only as identifiers

The concept assigns teal to S1, muted blue to S2, dusty mauve to S3 and charcoal to S4. Lock the final mapping in the bill of materials, pack card and quality checklist.

Colour is not a substitute for a moulded size mark or measured inspection, and colourfastness remains pending lot-matched rubbing and cleaning tests.

Require the exact material and hardness file

Obtain the polymer name for the body, neck, base and inlay; supplier grade; additives; pigments; bonding method; hardness scale and value; and applicable chemical documentation. Test every colour combination in the final construction.

Silicone, body-safe, hypoallergenic, phthalate-free, nonporous and waterproof claims are excluded until supported by traceable evidence for the finished set.

Start with an external fit and the smallest piece

Check the smallest base against the body externally before any internal use. Use only the approved compatible lubricant, move slowly, keep the entire T-base outside the body and never force a size or treat progression as a target.

Advance only after the previous size is comfortable and fully controllable. There is no required schedule, and skipping a piece is not a performance goal.

Set clear stop and escalation boundaries

Stop immediately for sharp pain, numbness, unusual pressure, bleeding, loss of base control, visible damage or any other concerning response. Do not use on irritated, injured or medically restricted tissue.

A retained item or significant bleeding requires prompt medical care. Product information does not replace advice from a qualified clinician.

Confirm lubricant and cleaner compatibility

Expose each body and inlay material to proposed lubricant and cleaner families for the validated contact time. Measure swelling, mass change, tack, colour shift, cracking, hardness change and bond failure after conditioning.

Recommend only combinations approved for the exact finished materials; water-based compatibility must also be confirmed rather than assumed.

Clean dry and separate the four sizes

Follow the validated wash temperature, cleaner concentration, rinse time and drying method. Clean each piece before first use and after every use, inspect the neck and base, then dry completely in a clean ventilated area.

Store the four pieces separated from incompatible materials and direct sunlight. Boiling, dishwashing, bleach, solvents and high heat are excluded unless the finished-set validation specifically permits them.

Monitor fatigue ageing and inlay adhesion

Run neck-bend, base-flex and inlay-bond cycles on S1 through S4 before and after accelerated ageing and repeated cleaning. Inspect for whitening, tack, cracks, permanent bend, edge lift, pigment transfer and dimensional change.

Discard any piece with damage, persistent odour, texture change, loose inlay, distorted base or an unreadable size identifier.

Build landed price from a four-piece benchmark

An Alibaba category page displayed one four-size suction-base plug set at USD 1.90 to 3.80 with MOQ 1. It is a broad public procurement benchmark only and does not identify this colour-coded T-base construction or an approved supplier.

The public procurement benchmark supports an EUR 39.99 planning price after provisional allowance for China-origin freight, four moulded pieces, colour inlays, measurement and progression checks, material and hardness review, lubricant and cleaner compatibility, base-retention testing, discreet fulfilment and expected quality loss. Exact supplier, quote, MOQ, packed weight, freight, duty, tax, certification, payment terms and lead time remain pending.

Frequently asked questions

How many trainers are included?

Exactly four separate sizes are planned, labelled S1 through S4.

Should I begin with the largest comfortable size?

No. Begin with an external fit check and the smallest piece, then move only when comfortable and fully controlled.

Can the colour inlay replace a size label?

No. The final product also needs a durable size identifier and measured quality record.

Is the illustrated material confirmed as silicone?

No. Exact polymer, grade, additives, pigments and hardness remain pending supplier documents and finished-sample tests.

Which lubricant can be used?

Use only a lubricant validated against the exact finished body and inlay materials; compatibility remains pending.

What if a piece cannot be removed?

Do not improvise with tools. A retained item, significant bleeding or severe pain requires prompt medical care.
