Return Policy

Effective October 20, 2026.

Request a return within 30 days

Email service@pervanzo.com within 30 days after receiving your order. Include the order number, item, and reason for return. For change-of-mind returns, goods should be unused and in their original condition, with packaging and included components where possible. Proof of purchase is required.

Return process

  1. Contact us before posting. We will identify the order and provide return instructions.
  2. Pack the item securely and include the order reference. Use a service that lets you keep proof of dispatch.
  3. Send the return to our company address below unless we give order-specific written instructions.

Return address

Hangzhou Yunteng Yisheng Network Technology Co., Ltd.
Room 1807, Building 10-1, South District, Wanyue City, Yunhe Street, Linping District, Hangzhou City, Zhejiang Province, China

This is an international return address in China. Consider postage costs before requesting a change-of-mind return. Our Hong Kong administrative business address is separate and is not the default return destination.

Who pays return shipping?

For personal preference or change of mind, the buyer pays return postage. If an item is defective, damaged or incorrect, contact us promptly with details and, where helpful, photographs of the item and packaging. We assess these cases individually and arrange an appropriate remedy, including return arrangements where required. Do not dispose of the item before contacting us unless safety requires it.

Inspection and refunds

After receiving a return, we inspect it and process an approved refund within 10 business days. Refunds go to the original payment method. Banks and payment providers may need additional time to post the credit. We will explain if a return is not eligible or an adjustment is proposed. Outbound shipping is not refunded for a change of mind unless required by applicable law; defect and incorrect-item cases are considered according to the circumstances and mandatory rights.

Exchanges and cancellations

Contact us to discuss an exchange; replacement availability is not guaranteed. The practical option may be a return and a separate order. For cancellation, email promptly before dispatch. A cancellation cannot be guaranteed after order processing has advanced.

Your statutory rights

This voluntary return policy does not exclude rights that cannot legally be limited, including remedies for goods that are faulty, misdescribed or not supplied as agreed.
