OEM · ODM Manufacturing

Your brand,
made in our factory.

From an idea on paper to a finished product on the shelf, we build it with you. WINIST is a manufacturer producing in its own factory in Cheongna, Incheon, South Korea — no trading company in between, so specification, schedule and quality all sit with one team.

01 What We Do

Hand us as much as you need.
Four ways to work together.

Whether your specification is already written or you are still deciding what to make, you can start from wherever you are. Pick the model that fits.

OEM

Built to your specification

Tell us the size, heat temperature and duration, and packaging format, and we produce and deliver exactly that.

When your spec sheet is ready

ODM

From design to proposal

WINIST takes on the design, proposes the product and manufactures it.

When you are still deciding what to make

Private Label

Under your own name

We print your logo and design on the non-woven pad, the pouch and the carton, so it is your brand's product from the start.

When you sell under your own brand

Wholesale

Proven products, in bulk

We supply WINIST's own brands — POPORANG, Loyalty Hot Pack, Mom's Hand and more — in bulk, as they are.
