Cốc tráng men

The stackability is what sold me — six of these nest into one tidy column in the cupboard, which my tiny kitchen appreciates. Enamel has that nice weight in the hand, and the kids' cups have already survived a few drops onto the patio.

Took these on a weekend camping trip and they survived being dropped on rocks and shoved in a pack without a single chip. The enamel keeps coffee hot way longer than I expected, and they look nice enough that I've started using them at home too.

The stackable design is what sold me — they nest tight enough that four cups take up barely any room in the camp bin. Enamel stayed cool enough to hold even with hot cocoa, and the kids didn't chip them once all weekend.
