If only they would STICK

Preface: for paper, these are fine. But in all honesty, my 5th grader is in the midst of the HydroFlask craze in addition to getting these stickers out to EVERYONE at her school through a fundraiser for a relative with cancer. The stickers are SO popular that the kids are putting them on their water bottles, and they do not stay on very well. The edges want to peel up right away. One wash and they'll slide right off. REALLY wish these were better based on how many we have bought and distributed already for the fundraiser. (HUNDREDS) I'll keep ordering because we've already started, but if another company comes along with better quality for the same price, I'll switch the orders elsewhere. Super sad.
