Kantong Es (Kotak Makan)

The two sizes slide right into my cooler bag without any awkward bulging, which makes packing lunch a breeze. Everything stays properly chilled through the whole morning, just the way I need it.

The slim profile slides into my lunchbox without cramping the sandwiches, and it truly keeps my yogurt cold until the afternoon. I tossed it in the freezer after breakfast and it’s been a solid addition to my workday rotation.

I’ve been freezing it overnight and throwing it in my lunchbox with yogurt and fruit, and everything stays properly cold until my afternoon break. The two sizes make it easy to fit snugly next to my water bottle without taking up too much room.
