Alcohol-Free Single-Use Stick Rinse (11ml × 5) The mouthwash where you can actually see it working. Now in a brand-new watermelon flavour. Okuchi's newest flavour arrives in the format that made the range a Japanese cult favourite: single-use stick sachets, no bottle, no measuring, no water needed afterward. Twenty seconds of rinsing lifts away the residue that brushing leaves behind — and yes, you'll see the result when you spit. Sweet, juicy watermelon, completely alcohol-free, and small enough to live in a handbag. Why You'll Love It Completely alcohol-free — No burn, no sting, no harsh aftertaste. Comfortable enough to use several times a day. You can see it working — The formula gathers and lifts protein residue in the mouth so it rinses away visibly. (How much you see depends on the state of your mouth at the time.) Reaches where brushing doesn't — Rinses across the whole mouth, including the spaces a toothbrush misses. Twenty seconds, no water needed — Rinse, spit, carry on. Nothing to rinse away afterward. Single-use sticks — Hygienic, pre-portioned, and genuinely pocket-sized at 12g per stick. Brand-new flavour — Watermelon joins the Okuchi range as one of its freshest additions. How It Works Protein residue is one of the contributors to an unfresh mouth. Okuchi's formula includes chitosan, a naturally derived ingredient with a gentle binding action: as you rinse, it gathers loose protein residue together so it lifts and washes away rather than staying behind. That's the reason for the range's slightly famous "look at what came out" moment. Supporting it: xylitol for a cleaner mouth feel, green tea leaf extract and propolis as traditional Japanese oral-care botanicals, allantoin to keep things gentle on the gums, tea tree leaf oil for a fresh finish, and citric and malic acid to help lift residue away. Who It's For Anyone who finds conventional mouthwash too harsh — this one has no alcohol at all Freshening up after coffee, lunch, garlic, or before a meeting Travel, long flights, gym bags, desk drawers, handbags Households looking for a hygienic, individually portioned option Anyone curious about the Japanese oral-care ritual that's quietly become a cult product How to Use Tear open one stick (11ml) and pour the full contents into your mouth. Rinse thoroughly for about 20 seconds. Spit out. No need to rinse with water afterward. Tip: Open the stick slowly and hold it upright — the contents can spill if torn quickly.
