why some mono speedy piping are wired but some are not? i'm also seeing variation in the materials as well. the piping on my speedy 30 is not wired, but my frd who bought a speedy 25 recently, her piping is very obviously wired (much thicker and holds the shape of the bag much stronger). And as for the material, hers is more flat, smooth, stiffer and thicker (i could barely feel the bumps on the canvas); whereas mine feels bumpy (like other mono bags that i own) when i touch it. so does anyone know why theres such a huge difference btw 2 speedies? aren't they suppose to be same? i kno they are handmade so there might be "shape" differences, but they should be made from the same material and use the same piping right? both speedies are authentic, purchased from LV store, but they look totally diff *really hoping for an answer* thanks!
