Customizable: Each volume contains 120 or 250 self-adhesive labels preprinted with your custom return address, perfect for sending personal or subject messages. Durability: Each 3/4 x 2-1/2 inch label can be used on any envelope and has a convenient self-adhesive backing for better holding, so you don't have to worry about the label slipping off the envelope or package during shipping. Because space is limited, the more text you add, the smaller the font size. Add label text to a script or block font using the Customize Now button. 3 lines of personalized information, such as name and address; Each line has a maximum of 25 characters
