A Mouth Broad x Citizen Ruth Collaboration! Balloons are weird, but here's one for this, the day of your birth. This A2 card measures 4.25" x 5.5" and comes packaged in a protective sleeve in packs of 6 complete with envelope. We also added a little wink on the backside of each card, just for an extra little bit of whimsy. These are printed on linen paper, giving each card an elevated look and feel, they feel luxe and will make any recipient feel special.
