We sincerely apologise if you are having any issues with our caps. To support you through this, we need some information from you. Could you send us a photo of the received caps and how many are affected to [email protected] so we can review them? We will appreciate your interest in collaborating with us on this. We're constantly looking for ways to improve the VistaPrint experience for everyone and this type of feedback helps us tremendously. We will remain at your disposal for further assistance.
