Designer series of Post-it Super Sticky Labels features a unique adhesive so your labels will stick securely to more surfaces and remove cleanly. The labels are perfect for the classroom and compatible with laser and inkjet printers. Each label has a double-lined, black frame with an arch at the top that is bookended by colorful blocks. Color-coded labels in colors of red, yellow, green, blue and purple allow students and teachers to color-code notebooks and other class materials by color. The large white space within the frame invites student names or other printed or handwritten identification. Each letter-size sheet of Post-it Designer ID Labels includes 15 labels (2" x 2-5/8").
