Keep track of your Covid vaccination card and prevent it from getting damaged by storing it in our branded holders. This durable vinyl 3.4" x 4.5" holder comes in many beautiful colors and features your custom imprint on the back, with a clear pocket on the reverse side. Show proof of being vaccinated to attend school, work, events, and travel - while promoting your brand! Recipients of all ages will be proud to receive our vaccine holders - an excellent and inexpensive way to encourage your audience to get vaccinated. To preserve the card, some people laminate theirs - but experts advise against this. Why? Laminating the card makes it impossible to add any new information in the future, like additional doses. Instead, experts recommend keeping it in a plastic sleeve or another type of holder.
