The only complaint: In my pink pencil case the zipper threatened on the open "end face", so that the closure would be open on both sides.
Typical zip disease that is known to prevent with a few pinpricks and a bit of yarn.
Nevertheless, 5 stars for the price-performance ratio!
In my pencil case I get 12 Fineliner, 3 pen, a great highlighter, 3x PostIt's Strip and an eraser, with no problems.
