噪音牛奶蓋（球）

The click it makes is so soft and buttery, almost like tapping a silk-wrapped stone. I keep fidgeting with it while I work, and the sound alone is weirdly calming. Definitely my favorite desk toy right now.

The velvety feel is exactly as described—it's soft and smooth without being slippery. The sound it makes is oddly calming, almost like a quiet whisper. I just wish the cap were slightly heavier for a more substantial presence.

The velvety texture is definitely unique, and the cap’s ball shape sits nicely under the thumb. That said, the "ethereal" sound it’s supposed to make feels more muted than I expected for the price. It’s fine for fidgeting, but not the standout I hoped for.
