We offer two sizes of water bottle labels, 2" x 4" and 2" x 8". The 2 x 4 labels are made to fit half-way around most standard size or mini single serving water bottles. The 2 x 8 are made to fit fully around a water bottle. Our labels are printed using 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 very easy to apply just peel and stick(no glue required). We personalize your labels for FREE! You may include a name(s), age(s), date(s) and/or any other specific wording. All orders include a detailed instructions sheet to better help you with your labels.
