Junk! These are so thin and flimsy.
On the left of my pic are super heavy duty, and they don't buckle.
On the right side of the same pic, are the ones I just received today.
They're so thin, they're flimsy, and must've been exposed to heat, because each sleeve is literally stuck together
Also, they're a very odd size. Look at the difference in height between the the good in the left. ,and the bad on the right. Both the bottom and height are so oddly sized, not only do they buckle, but you can't stand the notebook on its own ,
Return in progress.
