I recently purchased an agenda from a Louis Vuitton Boutique, and I noticed white stuff on the edges after I got home. One of the pictures isn't mine, but that's the same white stuff I had on my agenda. The white stuff was a bit sticky when I picked at it, and looked like dried glue. Is it extra glazing, canvas peeling, or something else? After picking at my agenda, my agenda now looks like that on the right. I am just concerned if it was defective or that I peeled of the coating on the canvas. Should I bring it back? Thanks!
