Maison 21G
Made in Singapore, Singapore, since 2019

Partly checked 29 Sept 2026. The official site calls it a French house; the Singapore founding comes from trade press. Founding year inferred from a 2021 article saying it was two years old. Older boutiques at Marina Bay Sands and Takashimaya not confirmed as still open.
