The dividers snap together to create the individual slots. Some reviewers said these can be easily cut to fit the exact measurements of your drawer.
Promising review: “I needed something to organize my socks, saw this, and thought it looked like it would work. I live in the Pacific NW where our winters aren’t particularly frigid, but they ARE cold and damp, so I tend to wear a lot of wool or thicker acrylic knit socks. This is exactly what I needed. Size is super, and it’s easy to put together once I figured out that the buttons are easier to get into the slots if you DON’T try to push them but instead rock them from side to side. Really, I couldn’t be happier with these. Much better than I expected, and exactly what I need.” —L. Mountford
