You have a lot of options when it comes to airtight food storage containers, but Progressive’s Prepworks models are unique in that they each include a special tool designed for a specific purpose. For example, the flour container has a built-in leveling bar, and the brown sugar container has a terra cotta disc built into the lid to keep your sugar from drying out.

Today, you can get a complete set of six containers (flour, brown sugar, powdered sugar, coffee, and two mini containers) for $36, an all-time low by a full $9.
