Blue Monday is one of the signature styles from the Luuna by Ulli Mahler collection, combining a clean, minimalist aesthetic with a focus on sustainability. Made from high-quality bio acetate, the frame reflects the brand’s commitment to responsible materials and refined design.

Each Luuna model is personally developed by Ulli Mahler, who designs every color combination as a standalone concept. The acetate sheets are produced exclusively for the brand, ensuring that each colorway is custom and never sourced off-the-shelf.

The result is a frame that feels considered in every detail—from its understated shape to its subtle palette. Blue Monday fits naturally into the language of quiet luxury: discreet, well-made, and thoughtfully designed, with attention to both style and impact.
