Hello @Seller_QVIUuxqiZ0ptT,

This is Josh from Amazon. Thank you for contacting our Forums!

I understand that you want to know more about how to make customized products for your listings. Don't worry, I got you.

Custom is a feature set that allows you to offer customizable and make-on-demand products to Amazon customers. With Custom, you collect configuration or customization requirements from the customer in order to finish the product before shipping.

Our current set of Custom features are free. However, as new features for Custom are released, charges may apply to the use of those features. Professional selling plan monthly subscription fees and referral fees will still apply while using Custom. For more information on fees, go to Selling on Amazon Fee Schedule.

If you are offering customizable or make-on-demand products, apply here.

Please go to Amazon Custom for more information.

I hope this helps. In case you need more help don't hesitate on contacting our Seller Support team.

Kind regards,

-Josh
