Review on Tools School Adjustable Removable Dividers Lab & Scientific Products by Russ Mashlan

This plastic is very hard and breaks easily. I was hoping for something more flexible like the plastic used in the Sterilite storage boxes. The rigidity of the plastic also makes it difficult to adjust the height and width when installing on lockers. Why is there a problem? Most likely, your child will assemble it without your help and install it in his locker at school. If your child is in high school, they may not have the thumb strength or patience to make adjustments. I would recommend doing a dry run at home to familiarize your child with the setup.
