There are a million different versions of this product that all look identical so you can pick who you buy them from. Just check the dimensions of what you're buying since there are many bigger than this that won't fit these size drawers.

I bought a 6 pack of these for $30 off amazon. They fit drawers between 11.8 and 17 inches. My sterilite drawers have a depth of 12" so they are almost fully compressed (and therefore, tight).

Because of their size, they probably take up like 5% of the drawer but if you're looking for a high quality divider for your drawers, these are pretty nice. Probably the least cost-effective method of dividing drawers though as there are a lot of cheaper ways to DIY this or buy different style dividers.

edit: I bought these but shop around as these seem pretty generic and a lot of people are selling slight variations of them in different sizes, quantities and prices. You can probably get a better deal than I did!
