How does THI handle refunds and returns?

The Happy Introvert creates on-demand, which means that all products are unique and produced per order. Returns or exchanges are not supported if you ordered a wrong size, color, or simply don’t like the product. We don’t have inventory space to keep unwanted items.

Once an order has been sent to production you can no longer edit any details or cancel it. However, we can offer a replacement order free of charge, if there are any issues with the order, like manufacturing error, printing issues and such.

In case you experience any difficulties, please feel free to contact our Support Team with all the necessary information and photographic evidence for an investigation, and we will do everything possible to correct the situation and provide the most suitable solution to you, depending on if the replacement or a refund is eligible or not.

What are THI's production times like?

Depending on several factors such as color, product type and the size of your item, production turnaround varies. Most orders are shipped within 2-5 business days from the order date.

How do I cancel or edit an order?

Because of the nature of print on demand, products are produced to order and are therefore non-refundable.

Once an order is in production, the order can no longer be cancelled, changed or edited as the item may have been created.

I want to cancel order

To cancel an order, you must let us know within 12 hours of when your order was placed. We will do our best to cancel any orders after this period but once production begins we can no longer cancel the order.

Sustainability & Responsibility

How do you plan to reduce the use of packaging?

  • We’ve eliminated the second layer of plastic packaging for all single-item shipments.
  • We’re testing the best paper tape to switch over from acrylic tape;
  • Adding recycling instructions to the poly mailer bags we’re currently using;
  • Looking for ways to replace plastic packaging.
