I own 2 wave bags (both in small size). One in pebble leather and another in smooth leather. I reach out to the pebble leather one more often due to it's color (grayish purple), and took her to short road trips etc. No scratches and pretty easy to maintain. I apply leather condition to all my bags so I guess that helps too. The shape hasn't changed much in my opinion....it's not a very rigid bag but the overall structure has maintained itself (e.g. it can still stand on it's own when it's empty, no folding or bending on the corners). The rubber pebbles are all intact and I don't see any scratches. Overall I am very happy with my 2 wave bags. It's a good size, very versatile, can be carried in many ways etc, I feel feminine and funky at the same time when I carry her
Hope this helps!!
