I used this once when my child went on a 12-day long cram school training camp. The carry case was only used on the road for about 2 minutes total, as I used a taxi for drop-off and pick-up. The scratches on the carry case, which occurred when it was loaded onto the training camp bus, are shown in photos 8 and 9.
