Ordering more adhesive bras can sometimes reduce shipping costs per item, particularly when a bulk shipment travels by sea. However, Xinrui does not provide freight quotes or calculations showing how costs change with order size. Also, the available specification does not confirm that the wing-shaped adhesive bra is silicone or medical grade: it lists spandex and nylon.
\nThe product record describes a butterfly-wing-shaped adhesive bra in skin and black, with sizes from A to D. Hand washing is the stated care method, and customization is available for color, size, and packaging. The listed materials are spandex and nylon; neither silicone nor a medical-grade designation appears in the product information. 
The shipping option affects per-unit freight costs. Xinrui identifies ocean shipping as the most cost-effective choice for bulk orders, while air freight and express courier are faster alternatives with higher unit costs. Since no rates are supplied for different quantities, buyers should request shipment-specific quotes before estimating savings.
\nFor recurring shipments above 30,000 pieces, Xinrui lists ocean freight as an option. Estimated transit is 28–35 days to the US West Coast and 32–40 days to Europe. Air freight is listed at 7–12 days to the EU and US, with customs clearance and last-mile delivery included in the described service. Express courier is estimated at 3–6 days to Europe and the US and is presented as suitable for samples or small spot orders.
