Stickers measure ~1.75-3'' depending on the design.
Please note that I do not recommend anymore that vinyl stickers be washed or be placed on a high-use area where it may rub against other objects (like on a phone or water bottle).
While they are waterproof, the edges of the laminate may peel up in these scenarios. However, I've had stickers on my monitor for almost a year now and they are in fantastic shape!
Items may appear slightly different in color/tone based on the device you are using. Please allow for some variance.
