Because I bought it at the Swarovski counter in Galeries Lafayette in Paris. The pen is equipped with a large rectangular blue paper box and a blue velvet bag specially for pens. Nothing else! It's definitely not the blank paper bag that the one who got the best answer said, and the statement that "there are two instructions and a warranty card" is even more nonsense! ! ! Swarovski simply stipulates that pens are not covered by warranty products! Where did you get the warranty card? !
