We're so glad to hear you were initially excited when you received the order and that you loved the print quality of the bags. That makes it all the more disappointing to learn that several of them had broken zippers, rendering them unusable. We are so sorry for this quality control failure, especially since these were meant as return gifts for your son's birthday. We want to resolve this for you immediately. To help us do that, could you pleas share a few photos of the bags showing the broken zippers? Also, confirm the total number of bags that were affected? This information will help us understand the extent of the concern and find the best solution for you. We apologize again for the inconvenience and look forward to making this right for you. If your request is urgent and you need an immediate solution, please reach out to our Customer Support team via https://www.vistaprint.com/customer-care/help-center/.
