スタックカップ（素材：

I bought a set for dinner parties and they stack so neatly you barely notice the extra height on the shelf. The base is designed just right, so the cups feel stable when stacked but still come apart easily without sticking. Definitely a smart upgrade to my usual tableware.

The tapered base makes these cups nest together perfectly without sticking, saving a ton of cabinet space. They also feel more substantial than my old everyday mugs, which was a nice surprise.

I love how the shape feels solid in my hand without being too heavy, and the slightly tapered design makes it easy to latch onto the cup below. It's become my go-to for morning coffee, and the stacking really does save space in my cabinet.
