collaborate with Narumiya International Co., Ltd.’s (headquarters: Minato-ku, Tokyo; CEO: Hiroyuki Kunikyo) popular brand Mezzo Piano to release four limited-edition products nationwide starting Wednesday, November 19th. [Official website] http://www.upink.jp/ [Available at] Official online store, Loft, Loft online store, Hands, Shop In, @cosme, AEON (some stores excluded) Package design (heart) that evokes nostalgia for the Heisei era, with a strong emphasis on “Heisei retro” Mezzo Piano is a hugely popular brand that led the Heisei era’s junior boom. Offering adorable items that embody girls’ aspirations, it remains incredibly popular even amid the current Heisei revival boom. This collaboration is the result of a collaboration between “Mezzo Piano,” which has provided many girls with romantic and sweet items that make them look their cutest, and “upink,” a cosmetics brand that encourages women of all ages to wear what they love and pursue “personal cuteness.” “Prism Jewel Glitter M101 Sugar Pink” is a glitter item that Yuki Kashiwagi has long wanted to release. For this collaboration, it will be released in a limited edition design featuring “Mezzo Piano”‘s popular character, Berrier-chan! The color is a soft white pink, and it contains fine glitter that shimmers with every blink. The moisturizing formula adheres perfectly to the eyelids without drying out. The ultra-fine brush allows for pinpoint application of glitter, even to the under-eye bags, making it easy to use even for beginners. The highly popular foundation “Cover & Glow Cushion M01 Light Beige,” which delivers stunning radiance and high coverage, and the wildly popular mascara “Fairy Curl Mascara M Black,” which keeps your lashes curled like a star all day long, will also be available in limited-edition collaboration packaging. The “Heisei Retro”-themed packaging evokes nostalgia for the 2000s. This design will bring back the excitement of those days and is a must-have for fans of “Mezzo Piano.” Additionally, the plump and lustrous lip oil “Dewdrop Lip Oil” is now available in a limited-edition color inspired by Berie-chan, “M102 Melody Pink.” This charming strawberry pink color combines silver and blue pearls with large gold glitter. The cute packaging features Berrier in a pink container, and the scent is as sweet as Berrier’s favorite strawberry sweets. A special lipstick that combines the worlds of “upink” and “mezzo piano” has been created. Be sure to check out this limited collaboration item that will tickle your girlish heart and get you excited just by holding it! *During the activity hours of the day Prism Jewel Glitter Product Details Image

The pink and silver base is packed with cute colored glitter. The thin tip makes it easy to adjust the amount even when applying directly to the eyes. When your makeup needs a little more work, just add this glitter and your face will instantly look complete! Even those who don’t normally use glitter will think it’s cute, so I definitely recommend giving it a try! Dewdrop Lip Oil Product Details

collaboration, and it feels like a dream to be able to work with Mezzo Piano, who I’ve loved since I was a child, and Berie-chan! All four products being released this time are collaboration-exclusive items, and we had many discussions and made them with a focus on “cuteness” down to the smallest details. I hope that fans of Mezzo Piano also think they’re cute (heart). Both the appearance and the contents are incredibly cute, so I hope that regular “upink” users, as well as fans of Berie-chan, will pick them up! And since they’re all easy to carry around, I hope you’ll carry them with you every day and enjoy putting them to use with your makeup! Limited time POPUP store details
