this review title is: slimmer chin and cheeks and the content is: these are thick jaw exercisers that really do work i have bought a few different ones of these but these are firmer and work better they come in their own carrying cases so you can take them anywhere i use the carrying case to sanitize them they can be cleaned with soap and water but the best thing i have found to use to clean them with is toothpaste and i sanitize them with mouthwash it gives it a better flavor when your biting down on them these have really helped with my double chin and have made my cheeks slimmer great value.there are other information for this review, one is this reviewer did purchase it and the other is 1 people think this review is helpful.
