Refund policy

60 Day Money Back Guarantee

Use it. Use all of it if you want to. If you're not happy with your first order, tell us within 60 days and we'll refund you in full. Keep the bottle — there's nothing to send back.

Not happy means whatever not happy means to you. The taste. The texture. The way the dropper sits in your hand. The way it fits, or doesn't fit, into a routine you've had for thirty years. How your teeth look and feel after two months of using it. Any of it counts, and you don't have to explain which one it was.

Eligibility

  • Your refund request must be submitted within 60 days of the date your order was delivered.
  • Proof of purchase — your order number or order confirmation email — is required.
  • Dissatisfaction of any kind is a valid reason. We won't ask you to justify it or talk you out of it.
  • Opened and partly used bottles are covered. That's the point: you can't judge it without using it.
  • The guarantee covers your first order of Kalvir Toothpaste Booster, and can be claimed once per customer.
  • If your first order was a multi-pack or bundle, the whole order is covered.
  • If you started on a subscription, your first delivery is covered. Later deliveries aren't — cancel any time from your account.
  • Repeat orders and replenishments aren't eligible. Once you've reordered, you've told us it works for you.
  • Requests submitted after the 60 day window aren't eligible.

How To Claim

  1. Email our support team at hello@kalvir.com with your order number. Tell us what didn't work for you if you'd like to — it helps us — but it isn't a condition of the refund.
  2. Our team will respond within 1–2 business days to confirm eligibility.
  3. Once approved, your refund is processed within 5–7 business days to your original payment method.
  4. You'll get an email confirmation once the refund has been issued.

Please Note

  • Original shipping charges are non-refundable.
  • Refunds are processed in the original currency of purchase.
  • Depending on your bank, it can take an additional 3–5 business days for the refund to appear in your account.
  • Kalvir reserves the right to refuse refund requests that appear fraudulent or abusive.

Damaged, Faulty Or Incorrect Orders

Separate to the 60 day guarantee, Kalvir will always make it right if something arrives wrong.

What's Covered

  • A bottle that arrives damaged, leaking, or broken in transit.
  • A dropper that doesn't dispense correctly.
  • An incorrect or incomplete order.
  • Product received past its printed expiry date.
  • Any packaging defect that affects the product's condition or usability.

What's Not Covered

  • Damage caused by dropping, crushing, or otherwise mishandling the bottle after delivery.
  • Product stored outside the recommended conditions — keep it at room temperature, out of direct sunlight.
  • Product used past its printed expiry date or beyond the period-after-opening marked on the pack.
  • Product purchased from unauthorised resellers rather than Kalvir directly.
  • Normal cosmetic marks to the bottle or carton that don't affect the product inside.

How To Report It

Email our support team at hello@kalvir.com within 14 days of delivery, with your order number, a description of the issue, and a photo where possible. We'll assess it within 1–2 business days and send a replacement or refund. You won't be asked to return the product.

Your Statutory Rights

This guarantee is offered in addition to, and does not limit or replace, the rights you have under the consumer protection laws that apply where you live.
