I received samples at the Osaka Healthcare Pavilion at the Osaka-Kansai Expo, but I won't be using them, so I'm putting them up for sale. I received them in mid-August 2025. They were stored at home for a short period, so please consider this before purchasing. This is a sample pack of alcohol-free oral care products, with 5 pieces per pack, for a total of 4 sets. - Product Name: MA-T System MOUTHWASH - Contents: 5 pieces x 4 sets - Features: Alcohol-free - Made in: Japan - Expiration Date: July 18, 2028 Thank you for viewing.
