Home cooks who pack lunches get meals that stay sealed and ready to reheat

Air-tight locking lids on durable microwavable plastic keep last night’s dinner from drying out on the counter or in the fridge. Open the same box at lunch and the food still looks like you packed it—then warm it without transferring dishes.

18 lock

Locks in moisture

The air-tight seal holds in steam and flavor so leftovers do not crust over before you sit down again.

18 shield check

Leak-proof for bags

A locked lid keeps sauces in the box, not on your tote, when you pack lunch on a weekday morning.

18 bolt

Reheat in the same box

Microwave-safe plastic means you skip the extra plate—warm the meal you already sealed.

Seal meals that stay fresh

Lunch that travels

Fill one box with tonight’s extra serving and lock it for the commute. The same set that lives in the fridge goes in the bag.

Fridge stacks, not piles

Four stackable sizes nest leftovers into a tidy column so you see what is ready instead of hunting under foil.

Microwave safe

Durable, BPA‑free microwavable container designed for quick reheating and everyday food storage.

Lock the lid instead of fighting wrap

Air-tight locking lids stack, seal, and go in the microwave. Wrap and open bowls do not.
