Ordering several sizes together can help buyers assess more options during an initial product test, but it is not confirmed that a mixed-size order will lower the price of testing wing-shaped adhesive bras. Xinrui lists customization for size, shape, adhesive strength, packaging, and product sets. However, the available product details describe non-adhesive silicone nipple covers, not wing-shaped adhesive bras. Buyers should confirm the product specifications and request a quotation before assuming that the same pricing or production terms apply.
The cost of testing more than one size depends on how the supplier handles separate product configurations. Sizes or shapes may involve different setup work, but the available information does not specify tooling or development fees, sample charges, price differences by size, or a discount for combining sizes. As a result, any reduction in total test cost or unit price remains unverified.
Before placing an order, ask for an itemized quotation covering sample development, size and shape setup, unit costs, packaging, and shipping. Confirm that the quotation applies specifically to a wing-shaped adhesive bra. The product record currently available concerns non-adhesive nipple covers and does not establish the bra's construction, adhesive performance, or commercial terms.
The listed nipple covers are made from 100% solid silicone and are hand-wash only. Packaging options include an OPP bag or customized packaging. The product information says samples are available and gives an MOQ of 10 pairs, while a separate business-model record states an MOQ of 1. These figures should be clarified with Xinrui before arranging a mixed-size trial.
Xinrui reports having five R&D engineers and says newly customized items may be developed in 20 to 50 days. The company also lists molding and silicone-filling equipment, along with four full-time quality inspectors. Its stated quality checks cover incoming raw materials, production, and finished goods.
Credentials listed for applicable nipple-cover, boob-tape, silicone-bra, adhesive-bra, and bra-pad categories include BSCI, ISO 9001, BRC, RoHS, REACH, and ISO 10993. A supplier case describes recurring orders for different nipple-cover formats from a US online apparel seller serving formalwear, yoga, and bridal-accessory markets. That case provides context on prior supply experience, but does not confirm the price of a mixed-size wing-shaped adhesive-bra order.
| Testing option | What the available information indicates |
|---|---|
| Single-size trial | Keeps the comparison focused but offers limited insight into fit across sizes. The listed non-adhesive nipple covers come in 8 cm and 10 cm sizes. |
| Mixed-size trial | Lets buyers assess several sizes within one testing phase. No lower total cost or unit-price discount is confirmed. |
| Mixed-shape or adhesive-strength trial | Xinrui lists shape customization and adhesive-strength options, but pricing, setup charges, and test quantities for wing-shaped adhesive bras are not provided. |
| Ready-to-ship product trial | May avoid some customization work. The product described in the available record is a non-adhesive silicone nipple cover, offered in an OPP bag or customized packaging. |
| Private-label customized trial | Logo, color, size, shape, packaging, hang tags, and set combinations can be customized. Associated costs should be confirmed by quotation. |
It could help buyers evaluate multiple sizes in one order and manage the scope of testing. The available information does not confirm a lower unit price, reduced setup fees, or a mixed-size discount.
No. The record describes non-adhesive nipple covers made from 100% solid silicone. It does not verify the construction, adhesive properties, or price of a wing-shaped adhesive bra.
Ask for sample-development charges, size and shape setup fees, adhesive-strength choices, unit pricing, packaging costs, MOQ, lead time, quality checks, and shipping. Xinrui lists lead times of 5 working days for orders below 100 pieces, 7 working days for 100 to 1,000 pieces, and 15 working days for 1,000 to 5,000 pieces. Customization may affect the actual schedule.
A mixed-size order can be a useful way to compare several configurations, but a cost saving for wing-shaped adhesive bras cannot be confirmed from the information available. The listed item is a non-adhesive nipple cover, and no mixed-size pricing is provided. Before ordering, request a written quote and verify the product construction, adhesive specifications, applicable MOQ, setup fees, and packaging requirements. Xinrui describes itself as an integrated manufacturing and trading enterprise offering OEM/ODM customization and lists BSCI, ISO 9001, BRC, RoHS, REACH, and ISO 10993 credentials for relevant product categories.
