We have set up a customer service team to provide services such as 3D modeling of design drafts, 48-hour sample delivery, and exclusive mold storage. During the cooperation period, we enjoy priority ordering and 15-day unconditional return and exchange for after-sales quality issues.

Equipped with an independent quality control laboratory, we implement the "three-inspection system" (raw material inspection, semi-finished product inspection, and finished product inspection). We use a German spectrometer to detect material composition, and manually screen polishing details for secondary screening, with a defective rate of less than 0.3%.

We support OEM/ODM small-batch customization, with a minimum order quantity as low as 50 pieces/style. Delivery will be made 20-30 days after payment, and real-time tracking service for production progress will be provided to ensure on-time delivery.

Haili uses 316L medical-grade stainless steel, which has passed the EU environmental certification, is nickel-free and lead-free, and is highly anti-allergic, so sensitive skin can also wear it with confidence. All products undergo a 24-hour artificial sweat test to ensure contact safety.
