Each label is an extra quarter inch in length in order to accommodate the largest array of hand fed meters. Great for your PB Postage Machine. All of our labels are packaged in high quality white boxes. Our boxes prevent damage from occurring during shipping and make it easier for you to store your labels. Many competitors labels are shrink wrapped because it is cheaper but they do not protect the labels from getting damaged and from laying loose all over the place once the shrink wrap is opened.
