The KOJA Guarantee

Matcha is a taste you buy before you can taste it. We carry that risk, not you.

90 days on the 90-day supply

Subscribe to the 90-day supply and you have the full quarter to decide. If it is not the best matcha you have had at home, one email within 90 days of delivery and we refund the box in full. No questions, no return shipping, no forms.

30 days on everything else

Tins, refills, samples, teaware and one-time orders: same rule, 30 days. Write to us, we refund.

Why we can afford this

Because the matcha holds. Sealed 30 g pouches mean the last bowl tastes like the first, and the batch data on every tin means you can check what you are drinking. People who try KOJA tend to stay, which is the entire business model. A guarantee like this is only expensive when the product disappoints.

How to claim

Send your order number via the contact page. Refunds are processed within 5 business days, back to your original payment method. The matcha you have opened is yours to keep.
