These water bottle labels are made to fit half-way around most standard size or mini single serving water bottles. They are printed with a commercial grade laser printer so ink is waterproof and will not run or smudge if water drips on them. Not recommended to be stored in a wet place as the labels may tear if they get too wet. Each label is self-adhesive and measures 2" x 4". Very easy to apply just peel and stick(no glue required). Each label can be personalized for FREE! You may include a name, age, party date, date of birthday and/or any other specific wording. All orders include a detailed instructions sheet to better help you with your labels.
