These containers have literally saved my sanity during road trips with my toddler. The 5oz jar fits exactly 12 goldfish crackers – which I know because I’ve counted them approximately 87 times while trapped in traffic.

The twist-lock system is so satisfying to use – it makes that perfect ‘click’ sound that assures me my kid’s yogurt melts won’t end up coating my diaper bag. Though fair warning: the seal is tight enough that I sometimes have to channel my inner Hulk to open them.

I never realized how much I needed stackable snack containers until these turned my purse from a crumb-filled warzone into something resembling organization. Now when my kid screams ‘SNACK!’ for the tenth time in an hour, I can just whip out the appropriate container like some kind of snack wizard.

The dishwasher-safe feature gets five stars from this exhausted parent. Though heads up – hummus does leave an oily residue that requires some extra scrubbing (learned that one the hard way).

Bonus unexpected use: The smaller containers are perfect for storing LEGO pieces when we’re out and about. Because nothing ruins your day like stepping on a rogue LEGO in a restaurant booth.
