A valid vaccination card is required for entry to so many of the places we go each day -- from school, restaurants, concerts and sporting events -- so it's best if your card is always handy. This fully customizable booklet has a double folded design to fit standard 4" x 3" government issued COVID-19 Vaccination Record Cards. A great idea for direct mail promotions, online offers, coupons, QR codes and much more. Choose from a range of cool colors and add your school, sports team, organizational or company logo or message to customize.
