Sustainability & Give Back

Water is life — and a central symbol of KOIY.

As a brand centered around water bottles and the rituals of drinking, we take our connection to water seriously. That’s why KOIY supports GAIN Germany and its “Wells for Africa” initiative. We build wells.

Together with GAIN, we help bring clean, life-saving water to communities in need across Africa. For us, this is more than charity — it’s a statement of values. Every KOIY piece sold contributes to giving others access to the most essential resource on earth: water. Because true luxury means being able to make a difference.

Sustainability is not a feature. It’s our foundation.

At KOIY, we don’t chase trends. We build timeless pieces — objects with presence, soul, and purpose. Sustainability isn’t something we add on top. It’s embedded in every decision we make: from design to materials, from production to partnerships.

We believe in less, but better. That means small-batch manufacturing, long-lasting quality, and products designed to be kept — not replaced. Each KOIY piece is made with meticulous care, using premium materials like stainless steel, natural leather, and (soon) glass — all selected for their durability, repairability, and beauty over time.

Our production process is deeply rooted in craftsmanship. We collaborate with European master artisans and specialized workshops that value tradition as much as innovation. Laser welding, gold plating, hand-polishing, and precise leatherwork — these are not just techniques, but a way of honoring human skill and slowing down the cycle of fast consumption.

We also believe in personalization as a form of conscious ownership. When something is made just for you — engraved, customized, refined — it’s more than an object. It becomes a part of your story. That’s what sustainability means to us: emotional connection, functional beauty, and radical quality.
