Croissant Birthday greetings card by Studio Boketto. A perfect birthday calls for a delicious treat! The smiling croissant birthday card has a 'Bon Anniversaire" caption for a little extra je ne sais quoi, adding to the bold design. The croissant birthday card is perfect for those carb-loving friends and family members of all ages, and the inside of the greeting card is blank so you can handwrite your own birthday message inside.
