Since everything that’s old is new again, this card is perfectly on-trend! This card’s got a retro vibe that’s expressed in different shades of blue that range from dark to neon. White font that is reminiscent of the disco era, though still understated and simple, expresses your wish for a “Happy Birthday” perfectly. Smaller than most other cards, this one measures at 5 1/2 X 4 1/4. An unlined white envelope is included with each card.
