Once LV style was changed into a beige and brown stripes design in 1876. In 1896, LV Company started the signature Monogram Canvas, and
made international patents on it.
This style adopted graphic symbols, including quatrefoils flowers and LV monogram.
In 1901, launched "Steamer" travel bag, which became the pioneer of handbags.
In 1909, Vuitton family used silk and wool to make "Kashmir" travel blanket,
which became the pioneer of scarf and quilt cover.
A good brand will always bring unlimited inspiration for the future, at the same time, a good brand will continue to be more classic with the time.
In 1914, finally opened the world largest travel leather products store in Paris. The store has seven floors,
which is very amazing. Based on the original principle,
continued to design more creative handbags. "Keepall" handbag changed people's concept about handbags.
The handbag made from canvas is so soft that people are not willing to put it down.
