  • Olga Muxart en su taller Mil.limetre en Barcelona

    Slow production

    All of Olga Muxart's pieces are made by herself in her workshop in Barcelona where she works under a slow production concept. She has small quantities of pieces in stock that are exhibited in her gallery-workshop in Barcelona. However, the fact that she works upon orders means that she does not have many unsold pieces to stock and, therefore, avoids generating waste.

    We care about our impact when packaging our pieces. For our jewelry, we use small cardboard boxes that are great to keep your piece of jewelry in when not in use. And for some special jewelry pieces we also make handmade ceramic boxes to add a touch of uniqueness.
