Pass the envelope to Canberra Balloons and leave the rest to us. We will open the envelope to read whether you are having a Baby Boy or a Baby Girl and decorate the inside of the box with a pink theme or a blue theme. The box will have a He or She foil balloon attached to the bow on the outside of the box. When the Surprise Balloon in a Box is delivered and opened an Its a Boy or Its a Girl balloon will pop up and reveal the sex of your baby. A perfect idea for a gender reveal. The white square box also contains a flutter of tissue paper, confetti and extra latex balloons in either pink or blue. The box is decorated with gorgeous ribbon and a handmade bow. You may like to add a teddy, a box of chocolates, and a bottle of wine to the delivery. Select them within the "Extra" category on the "Shop". Delivery within Canberra and Queanbeyan is included in the price.
