This is a very nice backpack.  It appears to be sturdy (only time will tell).  I gave the 4 stars instead of 5 because her last backpack was a bit larger.  She's in the 4th grade and that one was full all the time between reading books/school books/pencils pens etc.

08/09/2018-update-  I changed my 4 star rating to 5 stars because she has more room than I expected.  Everything fit's perfect/ it's very sturdy and I didn't realize the cat glows in the dark (although my granddaughter said it was in the discription!)
