You may not realize it, but by using the name Kleenex® as a generic term for tissue, you risk erasing our coveted brand name that we've worked so hard for all these years. Kleenex® is a registered trademark and should always be followed by a ® and the words 'Brand Tissue'. Just pretend it's in permanent marker. ® Registered Trademark of Kimberly-Clark Worldwide, Inc. ©2017 KCWW.https://www.kleenex.com/en-ca/
