The quality of the papers, the binding-EVERYTHING was FINE until... UNTIL, I finished the page: 378.... All of a sudden, the page: 443 appeared 😭. Then, it continues till the page: 458. SUDDENLY, the page: 395 comes into view 🤧....Then, it continues like nothing has happened in between.... (So, there's 16 pages are missing in total ☺️) My mental-peace has been stolen☺️👍🤧. This was my FIRST purchase.... *NOW I'M TRAUMATIZED* 😭
