If I could give this more stars, I would! It is incredibly sturdy and easy to use. I created my own numbered labels so that I could use them year after year (as opposed to using students' names, I wish I had a more close-up picture to show you). This chart is thick and durable. Each student in my class put 1-2 books in their pocket each day to have prepared for free-time or to read after lunch the next day. This chart didn't buckle or rip, and it had A LOT of weight in it at all times. I used (extra?) small command hooks to hold this up, one for each supporting hole on the top. Not only did the itty-bitty hooks hold up the chart all year without even budging, the metal rings on the pocket chart itself didn't even bend! I took this down to store it at the end of the year and you can BARELY even tell that it was used heavily all year. It really looks brand new.My only wish is that this came in different colors - such as grey or black. I know that there are other color options in charts that only have one column - but I really feel that the fact this chart has 3 columns helps to add to how sturdy it is. Having multiple charts hanging would make it easier for them to twist or turn.I HIGHLY RECOMMEND buying this!!!!!!
