We know teacher's hate to use the teacher voice, but sometimes its a must. Lets give some love to our teachers with this cute design. This must have teacher inspired sticker is approximately 3 inches X 1 inch. Made from automotive grade vinyl with an air channel adhesive to help avoid bubbles upon application. These are great to apply to laptops, water bottles, walls, and much more. Just know they are very sticky, and should last a long time!
