Q: What does the date code MI4148 mean on this item?
A: For Louis Vuitton pieces produced between 2007 and early 2021, the four digits represent week and year: the first and third digits are the week and the second and fourth digits are the year. Therefore, 4148 indicates production in the 44th week of 2018. The letters typically denote the factory code. Note that from 2021 onward, Louis Vuitton replaced visible date codes with embedded microchips on new production.

Q: How should I care for the quilted calf leather?
A: Wipe with a soft, dry cloth after use, avoid overfilling to preserve the quilting, keep away from water and oils, and store stuffed in a breathable dust bag, away from direct sunlight and heat to help maintain the leather’s shape and colour.
