Our law enforcement officers + personnel definitely do not get enough credit for the work they do each day to protect our communities. Each 12-pack of these appreciation cards includes 3 each of 4 different styles cards (blank on the inside) + white envelopes. These are standard A2 size cards - 4.25" x 5.5". These make a great project for people of any age to work on, and we can assure you they will be well received!
