Tupperware Thatsa® ミディアムボウル | 密閉・漏れ防止、19カップ/4.5L

Finally a bowl that actually seals airtight—I tested it with soup and tipped it sideways without a single drip. The scratch-resistant interior is holding up well against my metal whisk too.

The thumb handle makes it so much easier to carry this big bowl when it’s full of salad. The lid seals perfectly, and I’ve had zero leaks even when I tipped it sideways in the fridge.

I was skeptical about the 4.5-liter capacity, but it’s actually perfect for storing a whole batch of cookie dough. The lid snaps on securely and doesn’t leak at all, which is a huge plus for me.
