Ordering several sizes together can help buyers assess more options during an initial product test. However, the available information does not confirm that a mixed-size order for wing-shaped adhesive bras will cost less per unit or qualify for a discount. Xinrui offers customization for size, shape, adhesive strength, packaging, and product sets, but its listed product details describe non-adhesive silicone nipple covers, not wing-shaped adhesive bras. Buyers should confirm specifications and pricing directly before proceeding.
Whether combining sizes changes the cost depends on the supplier's production process. If each size or shape requires a separate setup, the order may involve additional charges. The provided information confirms that customization is available, but does not specify sample fees, tooling or setup costs, unit prices, or a discount for mixed-size orders. Any savings should therefore be treated as unverified until included in a quotation.
Ask for costs to be itemized before testing: sample development, size and shape setup, product pricing, packaging, and shipping. Confirm that the quote is for the requested wing-shaped adhesive bra. The product record currently available is for non-adhesive nipple covers, so it does not establish the adhesive bra's materials, construction, performance, or price.
The listed nipple covers are made of 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. Confirm which minimum applies to the specific product and test order.
Xinrui reports having five R&D engineers and says newly customized products may take 20 to 50 days to develop. Its production resources include molding and silicone-filling equipment, and it lists four full-time quality inspectors. Reported inspection stages cover incoming materials, production, and finished goods.
Credentials listed for relevant product categories, including nipple covers, boob tape, silicone bras, adhesive bras, and bra pads, include BSCI, ISO 9001, BRC, RoHS, REACH, and ISO 10993. A supplier case describes repeat orders for a US online apparel seller serving formalwear, yoga, and bridal-accessory customers. The case involved several nipple-cover formats, but it does not confirm pricing for mixed-size wing-shaped adhesive bras.
| Order approach | What the available information indicates |
|---|---|
| Single-size test | Offers a straightforward comparison but provides less information about fit across sizes. The listed non-adhesive covers come in 8 cm and 10 cm sizes. |
| Mixed-size test | Can assess multiple sizes in one testing phase. No reduction in total cost or unit price is confirmed. |
| Mixed-shape or adhesive-strength test | Shape and adhesive-strength customization are listed, but setup fees, test quantities, and pricing for wing-shaped adhesive bras are not provided. |
| Ready-to-ship product test | May avoid some customization steps. The product described in the available record is a non-adhesive silicone nipple cover, with OPP-bag or custom packaging. |
| Customized or private-label test | Logo, color, size, shape, packaging, hang tags, and product-set combinations can be customized. Associated charges need to be quoted. |
It may make it possible to evaluate several sizes in a single order, which can help manage the testing process. The information provided does not confirm a lower price, waived setup fee, or mixed-size discount.
No. The product record describes non-adhesive nipple covers made from 100% solid silicone. It does not verify the materials, adhesive properties, design, or pricing of a wing-shaped adhesive bra.
Request separate pricing for samples, size or shape setup, adhesive-strength options, units, packaging, MOQ, lead time, inspection, 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 can affect these timelines, so confirm the schedule for the requested product.
A mixed-size order may be a practical way to compare configurations, but there is not enough information to conclude that it reduces testing costs for wing-shaped adhesive bras. Before placing an order, obtain a written quote and verify the product construction, adhesive specifications, MOQ, setup charges, and packaging. Xinrui describes itself as an integrated manufacturing and trading enterprise offering OEM/ODM services and lists BSCI, ISO 9001, BRC, RoHS, REACH, and ISO 10993 credentials for relevant product categories.
