From a Shenzhen high-frequency bag factory in 1997 to a multi-origin supply chain partner for global beauty brands — nearly three decades of craftsmanship, evolution and trust.
Jinchen Supply Chain is the international sales company of King Fly International Development Co., Ltd., a manufacturer founded in Shenzhen in 1997 by Shirley Lee. Jinchen handles international enquiries and quotations, sampling, order follow-up and the Alibaba.com storefront, and it designs and assembles GWP and PWP beauty gift sets. King Fly handles material sourcing, production scheduling, pre-shipment inspection and export clearance. The two companies are separate legal entities founded by the same family, with no parent-subsidiary relationship.
King Fly runs a workshop of its own in Shenzhen, used for sampling and small runs, and works with long-term partner factories in China, Vietnam and Thailand — some of them for more than 15 years. Volume production is handled across that network, while our own QC team inspects every order before shipment.
We don't sell stock. Every piece is made to order: your design, your materials, your branding. In 29 years, no two clients have ever received the same product.
Jinchen Supply Chain and King Fly are two separate legal entities founded by the same family, with no parent-subsidiary relationship. Each one plays a distinct role, and together they cover the full journey from your first enquiry to the goods leaving port.

Shirley Lee enters the bag-making industry.
Zhanpeng factory established in Shenzhen, producing high-frequency pressed PVC and EVA bags.
Re-registered and renamed Shenzhen Zhanpeng Tourism Products Co., Ltd.
Began direct export — 22 years of independent exporting to date.
Jinchen Supply Chain established as King Fly's international sales company.
Serving beauty brands & promo agencies across 3 origins.
King Fly runs its own workshop in Shenzhen for sampling and small runs, and works with a network of long-term partner factories in China, Vietnam and Thailand. Several of these partnerships are more than 15 years old.
That mix is deliberate: our own workshop keeps material control and sampling fast, while partner capacity handles volume — and the multi-country base lets us offer tariff-advantaged origins for US buyers. Every order, whether produced in our workshop or at a partner factory, is inspected by King Fly's own QC team before shipment.
King Fly has manufactured in Shenzhen since 1997, and the manufacturing knowledge built in that first factory still sets our standards today. As the business grew across three countries, we moved volume production to long-term partner factories in China, Vietnam and Thailand, and kept our own Shenzhen workshop for sampling and small runs — so material control and sample speed stay under our own roof.
Our managed network gives you the best of both worlds: Shenzhen's speed and craftsmanship, plus Vietnam and Thailand's tariff-advantaged volume capacity.
Our quality standards are built for Japanese and European market expectations. Every order goes through three inspection stages before it leaves our network.
Certifications are held by our qualified partner factories and material suppliers, with audit reports available on request. Materials tested: AZO-free, lead-free hardware, REACH compliant, EU PPWR compliant, California CA65 compliant. SGS reports available on request.
Every material batch is verified against spec before production begins.
QC team monitors each production line, catching issues before they compound.
Every piece is checked before packing. Standard: 1pc/polybag, 5-ply export carton.
If it's a soft bag or accessory, we can make it. You specify the material — we source it, control it and deliver it.
A mother-and-daughter team: 41 years of manufacturing knowledge, and a new generation leading international business.
Shirley entered the bag-making industry in 1985 and founded the Zhanpeng factory in Shenzhen in 1997, which became King Fly International Development Co., Ltd. in 2003. She still leads material sourcing, production scheduling and pre-shipment inspection for key accounts, and works alongside Echo on day-to-day business. kingfly@kingfly.cc
Shirley's daughter. Echo has led the international business since 2025 — quotations, sampling, order follow-up, the Alibaba.com storefront, and GWP/PWP gift-set design and assembly. sales@jinchensupplychain.com
Between them: 41 years in bag-making, and client relationships built over the last 29 years.
For orders placed on Alibaba.com, your contract is with Jinchen (Shenzhen) Supply Chain Co., Ltd. and runs through Alibaba.com Trade Assurance. For direct orders placed with us outside Alibaba.com, the contract, invoice and shipping documents are issued by King Fly International Development Co., Ltd. (est. 1997), which holds the export licence.
For Alibaba.com orders, export and shipping documents are handled through Alibaba.com's Trade Assurance channel. For direct orders, King Fly International Development Co., Ltd. is the exporter of record, so the name on your contract, commercial invoice and bill of lading stays the same.
Because the work is split: Jinchen runs sales and gift-set development, King Fly runs manufacturing, inspection, export and collection. They are two separate companies founded by the same family, and we keep them that way deliberately — so you can see exactly which entity signs, ships and collects for your order.
MOQ is 500 pieces per style; trial runs of 300-499 pieces can be discussed. Sampling takes 3-7 days, or 3 days with stock fabric. Standard production takes 25-35 days. Expedited production of 10-20 days is possible when material is already available. Trade terms: FOB, CIF, DDP, DAP. Production in China, Vietnam or Thailand.
Whether you need 500 pieces for a pilot or 100,000 for a global campaign — we have the origin, the team and the experience to deliver.
