MARBLEDSALTS studio (formerly RL Studio) was established in 2019 by Roxane Lahidji, a social designer and artist specializing in material development and applications.

The studio’s work investigates the relationship between sculptural production and sustainability, developing research-driven projects that explore material transformation through environmentally responsible processes.

Born in Paris in 1992, Roxane Lahidji grew up in the French capital before studying illustration and product design at HEAR (Haute école des arts du Rhin) in Strasbourg. She graduated from the Social Design department at Design Academy Eindhoven in 2017, where she developed her project *Marbled Salts*, which laid the foundation for the studio’s ongoing research.

Her work has received international recognition: she has been awarded the FD100 prize three times, distinguishing her among the 100 best French international designers, and received the Bolia Award in 2019. More recently her *Yubiwa* table was recognized by Wallpaper* magazine among the “Best Elements of Surprise" and Sabato Design award in 2025.
