Hello. Thank you for reaching out to us.<br /><br />We are very sorry to hear that the adhesive did not meet expectations. To make sure the tape sticks, we recommend sticking it to a clean, flat surface. <br /><br />Your feedback is valuable to us and it will be forwarded to the appropriate department for further review.<br /><br />If you have any more feedback, please reach out to us via our Contact Us form on our website. We’re available Mon.-Fri. 9am - 5pm Eastern Time.<br /><br />Thank you!<br />DYMO® Consumer Care
