Interior greeting: For a day filled with joy. Printed on FSC-certified paper with soy-based inks in the USA. Paired with white envelopes. A6 card dimensions: 4.5" x 6.25". Please note that our greeting cards are pre-priced on the back in small print. If you prefer the added protection of cello, please note the option to add. Our cello jackets wrap around the card and envelope in a book cover-like style, allowing for the card's interior greeting to be visible.
