grrrr....how old was your Tulum before it showed signs of tarnish? The Lockit is my only LV (its the only one I like thats so sleek and distinctively LV yet doesnt scream LV) and Im super careful with it. I put it back on the dustbag after use. Even placed a pack of silica gel in the dustbag to prevent humidity from damaging the bag...and it saddens me that although my bag still looks new, I am seeing a tad of silver already (the lock still looks perfect though). I was tempted to bring it to the LV store but since youre telling me its normal, then I guess theres nothing I can, nor the SAs can do to change the fact that the hardware is just brass-colored! (I guess I misinterpreted the bag description!!!)
