MASH Beauty Lab Co., Ltd. (Chiyoda-ku, Tokyo / Representative Director Yoko Toyama YAMU) will begin operating the official WEB STORE "MASH GO GREEN STORE" on Wednesday, April 15, 2026, where all items developed by MASH Beauty Lab can be purchased. We will start selling a wide range of products including natural & organic cosmetics, inner care, food, and lifestyle goods, and will deliver the charm of natural & organic to even more customers.

### About MASH GO GREEN STORE

Everything from MASH Beauty Lab is here. A new WEB STORE is born.

Cosme Kitchen and Biople, which were previously separate portals, are now one. And 9 private brands, such as Celvoke and SNIDEL BEAUTY, have also joined. It is a place where all of our carefully selected "natural & organic" products are gathered.

Items with stories from all over the world will color your wellness days, and it will be reborn as a platform covering one of the largest lineups in Japan.

More freely, more deeply. A new experience where a natural lifestyle melts into your daily life, starting from here.

In this store, we will sequentially handle over 300 domestic and international natural & organic brands, including original brands such as "Cosme Kitchen", "Biople", "F ORGANICS", and import brands such as "Trilogy", "giovanni", and "Me Today". We will offer a wide range of categories including skincare, makeup, hair care, body care, inner care, food, and lifestyle goods, and will develop it as a place where you can enjoy natural & organic more closely.

Customers who previously shopped at each brand's WEB STORE will now be able to purchase them all together at "MASH GO GREEN STORE". Since delivery can be made at once, it will be more convenient and cross-brand shopping will be possible.

Furthermore, the number of products handled is planned to expand further in the future, and we will continuously update our lineup according to the season and time, including the introduction of new brands and the development of limited items. Utilizing the rich product lineup and convenience unique to MASH GO GREEN STORE, we will provide an environment where you can enjoy natural & organic more closely and easily.

### Evolving Products and Content as a Digital Flagship Store

We will further evolve this store as a digital flagship store, nurturing it into a place where you can enjoy new encounters and discoveries across brands. At the same time, we will carefully deliver the charm and thoughts of each brand through content and information dissemination, and as a bridge between customers and creators, we will expand comfortable online shopping experiences and warm connections.

### Service Development that Balances Convenience and Sustainability

In addition to being able to select products across multiple brands, we also plan to gradually expand our "subscription service," which allows you to deliver products from different brands together. We will develop services that enhance online convenience, such as saving the trouble of ordering from each brand and allowing efficient shopping with a single order.

Furthermore, purchasing products from multiple brands together leads to a reduction in shipping and packaging materials, realizing an environmentally friendly shopping experience. We will provide a mechanism that naturally leads to sustainable choices in daily shopping without undue effort.

### About Existing Apps and Points

- **Official App "GO GREEN MEMBER'S"** - The official app "GO GREEN MEMBER'S" will continue to be available after the opening of MASH GO GREEN STORE, and various services such as membership card functions, MA point confirmation and usage, and shopping through the app can be used as before. - **MA Points** - As before, MA card members can earn and use MA points awarded for shopping at the MASH Group at "MASH GO GREEN STORE".
