You do not want someone opening your drink without asking, or mixing it up with theirs. The fingerprint-locked smart bottle c-mon now answers that concern in a larger size. HASLUX Co., Ltd. released a 1,000ml model on July 22, 2026, priced at 7,975 yen (tax included). It comes with a carrying handle, and together with the existing 320ml and 500ml versions, the lineup now spans three sizes.
A Different Idea: Security for Your Drink
c-mon is a smart bottle whose lock can only be released by a registered fingerprint. Building biometric authentication into a bottle is an unusual idea, and its purpose is clear. In places where you briefly look away from your bottle, such as schools, offices, gyms, sports facilities, or the outdoors, it lowers the risk of someone opening the cap without permission, drinks getting mixed up, or tampering.
While keeping the insulation you expect from a vacuum flask, c-mon puts the idea of protecting what is inside front and center. This time, that concept gains a larger model that lets you carry more.
The 1,000ml Addition Brings the Lineup to Three Sizes
Until now, c-mon offered two easy-to-carry sizes, 320ml and 500ml. The new 1,000ml model is a large-capacity type aimed at situations where topping up is hard, such as sports, long outings, or a full day at the office.
The 320ml suits small servings or hot drinks, the 500ml is the everyday standard for commuting or school, and the 1,000ml is for when you want plenty to drink. The 1,000ml model has a handle on top so it stays easy to carry even as capacity grows. It comes in two colors: a calm matte black and a bright pure white.
Register Up to 15 Fingerprints, With Family Sharing in Mind
At the heart of c-mon is biometric unlocking with registered fingerprints. You can register up to 15 fingerprints, of which two can be set as administrator prints. You can register several of your own fingers, and the bottle also works for families who want to share and manage it together.
The technology that embeds biometric authentication into the bottle is registered as Patent No. 7812581 in Japan. The fact that it is a properly patented feature, rather than a novelty afterthought, is reassuring for this kind of unusual gadget.
Charge About Once Every Three Months, Easily Over USB Type-C
Biometrics may raise concerns about charging, but c-mon's battery life is long. It charges over USB Type-C, and on a full charge it is said to last about three months, assuming 20 open-and-close cycles per day (this varies with usage and environment). Because it charges with the same Type-C cable as your smartphone, there is no separate cable to carry. With no frequent charging required, it is easy to keep using day to day.

Summary
The 1,000ml c-mon pairs the fresh idea of protecting your own drink yourself with the practicality of a larger capacity and a handle. The peace of mind of a bottle no one else can open is exactly what helps in gyms, offices, and the outdoors, where it is easy to look away. With the convenience of about three months per USB Type-C charge, it is priced at 7,975 yen (tax included) and has been on sale since July 22, 2026.
