Lanvin’s Alber Elbaz loves the pencil crayons he uses to sketch his collections each season — so much so that he has designed a limited edition set. Called “20 years of Supracolor by Alber,” the boxed set shows a Parisian swinging her Lanvin shopping bags behind a red curtain while the lid carries a ringing endorsement from the designer. “My Supracolor pencils are more than a working tool. They are indispensable,” writes Elbaz, who was approached by Supracolor’s maker, Swiss firm Caran d’Ache, after declaring in an interview that they were his pencils of choice. The firm will put 1,988 sets, a nod to the year they were created, containing 120 pencils up for sale, first at Lanvin’s Fauboug Saint Honoré boutique on Thursday. The pencils will form part of the store’s window displays during Paris Fashion Week, before rolling out to other Lanvin doors plus select Caran d’Ache points of sale.
