Tiefossi was established in 2018. In the beginning, the founder just wanted to design a unique diary for his son. After the son showed it to his classmates, everyone unanimously recognized it, and the founder contacted the manufacturer to produce and sell it. In just a few years of development, we already have several product lines and have received positive feedback from the market. We have integrated product development, design and production, aiming to create excellent school supplies to serve students and office workers.
