   36 · Écrin
   Para joyería y accesorios de gama, donde la pieza es pequeña y el estuche
   es parte del producto. Crema de lienzo, oro del logo y tinta muy oscura
   solo para el cierre. La firma es el écrin: cada pieza vive dentro de un
   marco de doble filete de oro, con la etiqueta vertical corriendo por el
   borde. Nada de esquinas redondeadas ni sombras fuertes: filetes.
