Rock Solid Ez Top 小號 灰色

Snapped this onto my nightstand bottle and it hasn't leaked once, even knocked over on its side. The one-handed flip top is genuinely handy at 2am when I'm half asleep.

The one-handed open is what sold me — I can grab it in the dark without fumbling around. No leaks so far either, which is more than I can say for the last cap I had.

Wasn't expecting the leak-proof claim to actually hold up, but it's been rolling around my nightstand drawer for weeks with zero spills. The cap pops off with one thumb, which matters more than I thought at 2am.
