This is a set of letters (A-Z) and numbers (0-9) with a polka dot pattern as a background as well as part of the font.
All text is black. Backgrounds are red, orange, yellow, green, blue, light blue, purple, pink and grayscale.
I have used mine to label the door to my room and they are great for bulletin boards. The uses are unlimited.
