About Us

At Greenstone, we believe the finest taste begins where the ocean meets tradition.
From our own seaweed farms along Korea’s pristine coastlines to our state-of-the-art
manufacturing facilities, every sheet of 김 (kim) we produce reflects purity,
craftsmanship, and care. We grow, harvest, and roast our seaweed under the highest
standards — ensuring a crisp, clean, and natural flavor that captures the essence of the
sea. As both farmers and manufacturers, we control every step from tide to table,
delivering the world’s highest quality Korean seaweed — fresh, authentic, and
unforgettable.

What Our Customers Say

"A Flavor That Feels Premium and Authentic"

I’ve tried seaweed snacks from all over Asia
and the U.S., but Greenstone stands out
immediately. The crisp texture, clean
ingredients, and balanced seasoning show
that it’s made by people who understand
the craft.

Lina Park, Food Enthusiast & Nutrition Blogger.

“They Raised the Bar for Seaweed Snacks"

When we added Greenstone’s seaweed
snacks to our natural snack lineup, they
quickly became one of our top-performing
SKUs. Customers love the authentic Korean
branding and the subtle flavor variations
like Sesame and Original.

Their facility standards, ingredient sourcing,
