Perfume bottles and caps
This project marked their first collaboration with us for a completely new design. We didn't just find a factory; we provided an engineering-first approach. Our designers utilized Rhino 3D modeling and 3D printing to conduct rigorous fitment checks between the bottles and custom caps before mass production. We managed the entire ecosystem—sourcing the bottles, precision-engineered caps, high-mist pumps, and luxury packaging boxes.

No. We enforce NNN Agreements stamped with official Company Chops. We don't just relay messages, we act as your legal leverage on the ground to ensure contracts are binding.
We treat the 10th order like the 1st. We perform live video inspections on every single batch, never relying on the factory's self-check, ensuring no material swapping happens behind your back.
We lock costs upfront using BOM (Bill of Materials) contracts. Our Teochew negotiation advantage prevents suppliers from bluffing about raw material costs to justify hidden hikes.
Never. We represent YOU, not the supplier. We operate on a clear service fee and share original factory invoices for total transparency. We are supplier agnostic—we only care if they meet YOUR standards.
We qualify a Backup Supplier for every critical project. If the primary factory slips on lead times or high quotation, we can switch production immediately to protect your supply chain.
