Sero & Toni LINE Stickers are here!
Featuring a gentle 3D matte texture and soft natural lighting,
these stickers bring warm emotions to daily messages like
“Good morning,” “Thank you,” and “See you.”
Designed with care and a sense of play, each sticker is a small reminder to stay sensitive and alive.
From the Serotonin Institute—where joy and emotion matter most.
The first release features Japanese fonts.
More sticker series to come, inspired by seasons and moods.
