Depending on your business model, you might want to display a customized text field for all of your products on app. It could be a special instruction, VAT or shipping rule, or any other type of input you can think of.
After enable the customized text field, you are allowed to enter text in maximum 50 characters and choose the text color using a color picker. Customized text will be displayed in product list, product details, and related products. Except for product details, customized text in other places will be truncated if it exceeds two lines.
