Return & Refund Policy

Last updated: November 6, 2026

Tethira (tethira.com) is owned and operated by RAY POWER TECHNOLOGY TRADING LIMITED. This policy applies to purchases made from our store and does not limit your mandatory rights under applicable consumer law.

1. Return window and eligibility

You may request a return within 30 days after receiving your item. For change-of-mind returns, items must be unused, unopened, in their original packaging, and have all original seals intact. Please provide your order number or proof of purchase.

Opened or used cosmetics and personal care products are not eligible for change-of-mind returns for hygiene reasons. Gift cards and clearance items are also excluded from change-of-mind returns. These exclusions do not affect your rights for damaged, defective, incorrect, or otherwise nonconforming goods.

2. Requesting a return

Before sending any item back, email support@tethira.com with your order number, the item, and the reason for your request. For damaged, defective, or incorrect items, include photographs if available. We will review your request and provide return instructions for eligible items. Please wait for these instructions before shipping.

US return processing address (authorized returns only):
Rose Niederhauser
10181 NW 51st Lane
Doral, FL 33178
United States

This is a return processing address, not our company registered office. Our Hong Kong registered office is not a designated return location. Do not send returns to that office unless we specifically instruct you to do so.

3. Damaged, defective, or incorrect items

Please inspect your order after delivery and contact us promptly if there is a problem. We ask that visible damage or incorrect items be reported within seven days to help us investigate; this request does not limit your applicable legal rights. For verified damaged, defective, or incorrect items, we will cover required return shipping costs or arrange an appropriate replacement or refund.

4. Refunds

We will notify you after receiving and inspecting an eligible return. If approved, we will issue the applicable refund to your original payment method within 5-10 business days. Your bank or payment provider may require additional time to display it. Contact us if a refund has not appeared after the expected processing period.

5. Changes and cancellations

Email us as soon as possible if you need to change or cancel an order. We will try to help before fulfillment begins, but changes and cancellations are not guaranteed once fulfillment is underway and may not be possible after dispatch. Eligible items may be returned under this policy.
