For the best presentation, dark inks are recommended. Please note that this is a tri fold card in which customization may occur on the left, right, and inside panel. When customizing, please note that only one ink color may be selected for your personalization. Printing in two or more ink colors is available for an additional charge. Please inquire with customer service for details. This card includes white French flap single envelopes. The impressive presentation of a French flap envelope requires extra postage when addressed vertically.
