This big black balloon is the best way to celebrate during a gender reveal party! This kit comes with everything you need (as long as you have a friend to help out!) for your special gender reveal! The balloon is 36" so it will definitely make a big impression! The set comes with both pink and blue confetti, just use the color that will be the reveal! Once you and your friend have filled the balloon with confetti, inflate and tie together with the black string provided. Congratulations on your new addition! This wonderful Brooklyn based company, Knot & Bow curates inspiring wrapping supplies and accessories-so that you can enjoy crafting and wrapping with a lovely collection of bits and pieces!
