About Modern Problem
Every item is carefully chosen with a clear purpose and a thoughtful intention. What began as my passion project years ago has steadily grown into something far more meaningful. I travel the world collecting interesting art and objects—vintage and modern pieces from California, Japan, and beyond—curating a varied mix that reflects different eras, cultures, and unexpected stories.
