It was arrived missing screw and it wasn't stand straight. I purchased from Amazon. When I went to the mall and saw same rolling backpack and it was stand fin and no missing screw so I cannot give 1 star, 2 star is most.
One more reason is some how this backpack's handle I pinched my finder skin few times.

I returned(Thanks amazon! it was easy return) and purchased 1 hand rollin backpack from same Olympia. It cost $10 more but it away better. It's more drable and solid some reason (it's same company!). The handle can adjustable 2 position so when my son rolling short and I can roll longer position. Which kids not taking lot of space when rolling bag to get others annoyed.

Well this is for kid's school bag so it's should be strong and drable for everyday. I recommend other 1 hand rolling backpack from same Olympia.
