Drawer organizers tend to be durable, flexible pieces that are made to obstruct your drawers as little as possible and stay clean as best as they can. Because of this, plastic is a commonly used material for drawer organizers. It's thin, it's flexible, it will last for a very long time---and it can often be molded to many different shapes of drawers, so it can be used for a variety of differing purposes.
On the other hand, plastic may not be very pretty. If aesthetics are important in your quest for the perfect drawer organizer, selecting a stained wood drawer organizer may be a much better choice.
Which organizer you should purchase will depend upon the amount of drawer space you have, as well. For example, because of the longer length of the pegs, larger food storage customizable organizers may not work well in shallower drawers.
Pay attention, too, to the width of the drawer organizer. Many will be able to expand to fit wider drawers, but they likely won't be able to collapse beyond a certain width. Taking the time to measure your drawers against the minimum width of the organizer can save you a lot of time!
