We recently introduced the option in Ink cards to send a Premium Ink card with an envelope. For a 2.99 upgrade (plus the card's 1.99 base cost) you can send an Ink card on heavier card stock with a matte finish all in a premium envelope. You can of course still use the same app to send the same 1.99 Ink card you've come to know and love. There is a "switch" at several points during card creation that can be used to flip your card between the two formats before placing the order.
