Yuki Kashiwagi's Comments on the mezzo piano Collaboration

This is upink's first character collaboration, and being able to work with mezzo piano and Berrie-chan, whom I've loved since I was little, feels like a dream come true! All four products being released are collaboration-limited items, and we discussed many times to ensure every detail is made with "cute!" in mind. I'd be happy if mezzo piano fans find them cute too. The look and contents turned out sooo cute, so I hope not only regular upink users but also Berrie-chan fans will pick them up! And since they're all easy to carry, please carry them every day and enjoy your makeup!
