In short

KUBO Jewelry is a Guangzhou-based stainless steel jewelry manufacturer working exclusively in B2B custom production. The company develops OEM, ODM and private label collections for brands, retailers and wholesalers worldwide — with the largest share of clients in North America, Europe and the Middle East — handling sampling, bulk production, finishing, branding, quality inspection and export from one location.

Why a specialist rather than a full-service factory

Most jewelry factories in Guangzhou produce across silver, brass, zinc alloy and stainless steel. That flexibility is useful when you need a mixed-material collection, but it also means the stainless steel line is one of several, competing for the same tooling time and the same polishers.

KUBO does stainless steel only. Two consequences follow, and both matter to a buyer:

The finish catalogue is genuinely available. Colours such as champagne, gunmetal and deep black are achievable across a material where colour consistency between batches is difficult. A factory running stainless steel occasionally will quote those colours and then struggle to hold them across a reorder.

Tolerances are repeatable. When the same material runs through the same polishing and plating lines continuously, the second order matches the first. That is the difference between a collection and a one-off purchase.

How we work with a brand

We are set up for overseas buyers working at a distance:

  • English-language specification documents at every stage, so nothing depends on a phone conversation being remembered correctly.
  • Photo and video updates at defined milestones — after tooling, after first sample, at pre-plating, at packing.
  • A single contact who owns the project from brief to shipment, rather than a handover chain between a salesperson and a merchandiser.
  • Export documentation prepared in advance, with shipping terms agreed before production rather than negotiated at the port.

The honest limits

We are not the cheapest quotation you will receive. If your only variable is unit price, there are factories that will undercut us by using thinner walls, lighter plating or cheaper clasps — and the finished product will look right in a photograph and fail in a customer's hand.

What we offer instead is a supply relationship that survives a reorder and a retail partner's quality inspection. For an independent brand building a reputation, that is usually worth more than the difference in unit cost.

Where we are

Guangzhou, Guangdong Province, China — in the Pearl River Delta, within reach of the region's casting, polishing and plating supply chain. That proximity is why we can control finishing quality rather than merely subcontract it.
