We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.

To be eligible for a return, your item must be in the same condition that you received it, unused and in its original packaging. You’ll also need the receipt or proof of purchase.

To start a return, you can fill in the RMA form at https://www.us.contrinex.com/pages/rma If your return is accepted, we will contact you with instructions on how and where to send your package.

Please note that shipping costs are at your charge and items sent back to us without first filling in the RMA form will not be accepted.

You can always contact us for any return question at customer.service@contrinex.com

Damages and issues
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.

Exceptions / non-returnable items
Certain types of items cannot be returned, like custom products (such as special orders or personalized items). Please get in touch if you have questions or concerns about your specific item.

Unfortunately, we cannot accept returns on sale items.

Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

Refunds
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too. This usually takes about 10 business days.
