This Demo is using a third party Premium plugin for POD products.
That means that you will have to purchase a subscription to a third party company in order to get this feature enabled, but trust us when we say that it is the best one out there and it's worth every penny if you plan to start a Print on Demand business. Customers can personalize any item in your store before purchasing it by adding their own images, colors, and text. With the live, 3D preview feature your customers will always know how their personalized products will look like. You can use the customizer for phone cases, t-shirts, hats, hoodies or any other product.
