So so
It came in perfect condition but the reason I wont give 5 stars to this product is just because it is not super sturdy I used it for about 2 years and the closing mechanism now is not functioning properly. You might say 2 years is a lot and you are absolutely right but comparing to the lifetime of a binder.. Regardless it was well loved while it lasted!

Excellent little binder for my school notes
It's a delicate binder and should be handled with care, but I think it's worth it. It is incredibly slim, and after I figured out the ring mechanism, I never want to go back to metal binder rings. The only thing I haven't liked is that the cover is so flexible that you really have to use the notebook on a flat surface; however I took a few minutes to DIY a shitajiki insert to add stability and it's perfect. I'm going to order more in other colors to hold old notes and journal pages.

Lies! (Read All)
This description is a lie. It holds way more pages than I anticipated. I was turned off by the 25 page limit but thank goodness I decided to purchase because it fits a lot of pages. Just buy the looseleafs in A5 size which are avaialable on Amazon for 6.5 bucks
