I recommend Dr. Bronner's tongue cleaner.

Hello. The product I would like to recommend today is the Dr. Bronner's tongue cleaner. Honestly, no matter how hard you scrub your tongue with a toothbrush, it only causes pain in your arm and wrist, and it doesn't clean as thoroughly as we hope. So, if you use this tongue cleaner, you simply grab it with your hand and push it back to clean it, and you'll get a clean tongue. Then, your breath will smell less bad, right? I know there are probably many people around you who suffer from bad breath, so please make sure to recommend this to them.
