Your review: I have purchased over 30 of the compartment boxes. We use them to create a wire terminal kit for a large customer. The removeable compartment section is made of a durable plastic type material, and the bottom of each compartment is rounded so that it's easy to remove the contents without having to navigate around a sharp, right-angel corner. For what this box costs, it's a very good value. The only caveat that I would provide is that the metal portions of the box are made from a rather thin gauge metal that flexes very easily and would be prone to bending if the boxes is handled too roughly. For most applications, this isn't an issue. Our customer loves the box, so we will continue to purchase this box for future orders.
