غطاء منزلق

Didn't think a lid could make much difference, but this one seals way better than the old one I was using. The slide glides open one-handed while I'm driving, and it hasn't dripped in my bag yet.

The splash-resistant seal is exactly what I needed for my desk—I've knocked it over twice and not a drop escaped. The lid contours to the cup so snugly that I forgot it wasn't the original one.

The slide mechanism is so satisfying—it glides open with one thumb and snaps shut with a tiny click that actually feels secure. I've knocked it over twice already and not a drop spilled, which is more than I can say for any other lid I've owned.
