OSAKA, Japan (May 8, 2026) — Sweet Co., Ltd. (CEO: Midori Kayama) is excited to announce the launch of "SWEET 1MONTH," the highly anticipated monthly edition of its best-selling color contact lens series, "SWEET 1DAY," debuting on Friday, May 8, 2026.

This new collection features SANA, MINA, and JEONGYEON of TWICE as brand ambassadors, showcasing three distinct lines that celebrate their unique individualities. Each line offers a versatile lineup of six colors (including exclusive limited editions).

"SWEET 1MONTH" perfectly balances stunning aesthetics with exceptional cost performance, making high-fashion eye looks effortless for daily wear. The collection will be available via Sweet’s official online store, major e-commerce platforms, and Don Quijote stores.

Finally Here: The All-New "SWEET 1MONTH" Monthly Collection.

■ A New Way to Shine: Introducing "SWEET 1MONTH"

The "SWEET 1DAY" series has long been celebrated for its diverse lineup, offering three distinct brands crafted to meet every style and need. To build on this success, "SWEET 1MONTH" was born—designed for those who want to embrace the series’ iconic aesthetic as part of their daily routine.

While staying true to the most-loved colors from the 1-DAY collection, this new monthly edition features evolved designs that create an even more striking and impactful gaze. By preserving the unique charm of our three signature brands, we are proud to offer a new way to experience color lenses—allowing you to stay effortlessly "you," every single day.

■ The Spirit of the Brands

The new "SWEET 1MONTH" collection captures the essence and beloved designs of the original three "SWEET 1DAY" brands, reimagined for daily wear.

SANA, MINA, and JEONGYEON perfectly personify "Beauty That Is Uniquely Your Own," bringing three distinct aesthetics to life. This series is designed to make the confidence, radiance, and inner strength found in your eyes a part of your everyday style—turning your natural charm into a daily standard.
