[Lock & Lock] All-Fit Thermal Korean Lunch Box


Today, if you’re looking for a lunchbox made for Korean meals… look no further.

This dosirak (Korean lunchbox) was built with you in mind.

First, you need a proper container for rice. And let’s be honest — no Korean eats cold rice. That’s why this rice container features double-layer thermal insulation. It keeps rice warm for up to 11 hours. So when you open it at lunchtime, it’s still enjoyable. Of course, not piping hot like it just came out of the rice cooker — but warm enough to truly enjoy with your thoughtfully prepared banchan.

Next comes the soup or jjigae container. For Korean meals, this one is essential. And it has one job above all else: not leaking. Work is hard enough already — why add the stress of worrying whether your kimchi jjigae has spilled inside your bag and scented your entire office? This container is completely leak-proof.

The third container is for banchan. And what makes banchan taste best? When it’s warm. Lock & Lock thoughtfully designed this container to be microwave-safe. Made from Tritan, it’s 100% safe to heat in the microwave.

Everything comes neatly packed in a clean, minimal bag — no flashy colors, no cute designs. Just something that works, for both men and women.

And yes — spoon and chopsticks are included.
