I saw it also for the Speedy B on the website as brass but for example the new Caissa Clutch which has a substantial chain or the Pochette Felicie appear to be coloured metal - my SA in Germany warned me that the Felicie chain would fade as it was only coloured.My newer items, bought last 2 years are made of two different qualities, one that reminds me of my Skultuna brass items and ones that are just plated and fades to silver.. I've been at Louis Vuitton in Stockholm and they say the metallic pieces fades like this which is bull****, the older items are much better. My dogs collar is 4 years old and the metallic pieces still has a brown/ golden color, after all this years in snow and rain.. But his new lash from this xmas is fading to silver!!
I don't know if you have noticed that they have changed the description from "brass pieces " to "gold colored metallic pieces" on the website. It's just on the keepalls without shoulder straps, and mon monogram items that still is "brass pieces "
