An exact long-format trainer, not a generic short plug
SMOOTH JS-YL174 is a black, highly flexible, ribbed and gradually widening trainer with a tapered tip and flared suction base. The six images on this page come from Alibaba offer 1601601202761 for the same model; none is generated, recoloured or substituted from another product. Its unusual length and progressive profile make careful specification checks essential.

S, M and L are supplier labels rather than body-size promises
Three selectable variants mirror the live offer: S, M and L, all Black. Only S has a readable measurement image. M and L are offered as supplier-labelled options while their total length, diameter progression, weight and base dimensions remain pending written confirmation.
The S diagram provides a limited set of measurements
The S image states 80 cm total length, a 1.8 cm tip width, graduated shaft widths of 2.2, 2.4 and 2.6 cm, a 3.5 cm base width and 345 g weight. These are marketplace diagram values, not independently measured sample results. The listing’s 0.3 kg gross package figure conflicts with the 345 g product wording and cannot both describe the same packed unit.

The ribbed profile expands gradually along the shaft
The surface uses closely spaced ridges over a long taper. That geometry may create substantially more friction and stimulation than a smooth shape. No customer should treat the full visible length as a goal, and the larger sections should never be approached merely because they are present.
The suction base is an external anchor, not a safety guarantee
The flared end is shown attaching to a smooth surface. Suction strength, release force and durability are not published. Keep the entire base visibly outside the body and within direct hand control at all times; never rely on wall, furniture or floor suction as the only means of control.

Material identity and grade are still pending
The supplier title calls the item soft, but the live page did not provide a reliable material composition or grade. No silicone, TPE, latex-free, phthalate-free, body-safe or medical-grade claim is made. Procurement must obtain a signed bill of materials and test evidence before paid sale.
Cleanability depends on seams, voids and material evidence
The marketplace says waterproof, yet no rating, method or report was supplied. A sample needs close inspection for mould lines, pores, hollow sections, openings and inaccessible creases. Cleaning instructions, permitted water exposure, disinfection limits, drying time and storage method must follow the confirmed construction.
Lubricant compatibility cannot be assumed
Use only a lubricant type approved in writing for the confirmed material. If that evidence is not available, the product should remain a preview item. Solvents, oils and unsupported cleaners may change a soft compound, surface texture or suction base.
Begin with control, not distance
This long-format design is not positioned as a beginner item. Any future instructions must prioritise a small, comfortable starting section, abundant compatible lubricant, slow manual control and constant access to the external base. Never force progress or use the product while sensation is impaired.
Pain, bleeding, numbness or dizziness means stop immediately
Discomfort is not a training milestone. Stop at once for sharp pain, persistent pressure, bleeding, numbness, weakness, dizziness or unexpected resistance. Seek appropriate medical help if symptoms continue or if any part cannot be removed safely.
The visible total length is not an insertion target
The supplier markets an extra-long format, but a product dimension does not create a safe-use objective. The external base must remain outside and directly reachable. Never allow another person to apply force, rapid movement or uncontrolled depth.
The public product-cost range is EUR 7.31-12.89
The offer shows that range with a three-piece MOQ, but its exact tier mapping was not reliable enough to declare a firm 200-piece unit cost. A written quotation must identify S/M/L mix, Black colour, packaging, batch, inspection terms and quotation validity.
The EUR 54.99 price is a provisional retail plan
The logistics panel displayed three pieces at EUR 21.44 beside a separate EUR 41.44 figure with unclear basis. Neither is a 200-piece China-to-Portugal quote. The planning price reserves room for freight, clearance, duty and VAT where applicable, discreet packing, high-risk sample checks, payment costs and quality loss.
Sample acceptance needs destructive and dimensional checks
Procurement should measure every size, weigh packed and unpacked units, inspect the entire surface and base, verify flex recovery, pull strength and suction consistency, and record material and batch documentation. M/L specifications, carton data, warranty, Incoterm and payment terms remain pending.
Frequently asked questions
Which variants are available?
The exact offer presents S, M and L in Black, and all three are selectable in this preview.
Is every size one metre long?
No such claim is made. The only readable chart identifies S as 80 cm; M and L dimensions are pending.
Is this product made from silicone?
That has not been confirmed. Material composition, grade and test evidence are required from the supplier.
Can the complete length be inserted?
The total length is not a use target. The flared base must stay outside and directly reachable, and no force or uncontrolled depth is appropriate.
Is the suction base proven?
No quantified suction or durability evidence is available. Treat it as a positioning feature, not as a safety guarantee.
Are these the supplier’s exact images?
Yes. Six images link to offer 1601601202761 and retain the exact Black product without AI restyling.
