I received the bottega padded cassette in caramel today (calfskin leather). It’s gorgeous. However I noticed these creases on both sides of the bag where the straps are located/ stitched to the inside of the bag. The creases are on the exterior. Would this bother you? Should I keep it or return it (knowing that I won’t find this bag in calfskin leather, since they’re all made in lambskin now)?
