Rubbermaid Brilliance is your yogurt lunchbox

If you actually want yogurt to survive a trip in a lunch bag, skip the bento boxes and buy Rubbermaid Brilliance food storage containers. They’re the best leak-proof option under $20.

What matters is the container, not the lunch box itself. The Brilliance has four locking tabs that snap down over a silicone gasket, so the seal is genuinely watertight. You can hold it upside down with yogurt inside and nothing moves. The plastic version is cheap — usually $8–$12 for a 2-cup, and the glass version also stays under $20 if you prefer that.

Bento boxes are the trap. They look convenient, but most compartments aren’t individually sealed, so liquids leak from one section into another. That means yogurt in your grapes. The Brilliance is built for wet food, so use that instead.

Get the 2-cup size for a normal yogurt serving and you’re done. This is the rare case where under $20 gets you the genuinely good thing.
