Printed on 270 grams Environment Birch paper: off-white paper with a small fiber in it. Environment Birch is FSC certified and produced without the use of optical brighteners like chlorine and consists of at least 30% post-consumer recycled fibers. With subtly rounded corners. The size of the card is A6 (105x148mm). On the back, as always, are some details from the illustration plus The Lemonbird logo, otherwise the back is blank. Note: Would you like a recycled kraft envelope with it? You can order it separately.
