RubbermaidLock-Its Square Food Storage Container with Easy Find Lid, 2 Cup, Racer Red 1776414

If this container stain-resistant?

Can I get 14 cup container

Is the 9-cup container suitable to store a 4-lb bag of granulated sugar? Are dividers in the 9-cup size? Pls only comment if you use it for that!

What are the dimensions of the 1 cup and 3 cup sizes of the Rubbermaid Lock-It’s?
