I bought this to store my wee son's pens and pencils in so he could see what was in there and keep them all together but separated out into different kinds. I was expecting it to be sewn together at the seam but it is sewn together in a rectangular shape in the middle through the plastic. This is fine though as I doubt it will be experiencing any rough play. I will be buying another one to store his crayons and chalk together as well. Ideal for my purposes.
