The OctaLock seal is noticeably tighter than my old lid—no more dribbling when I tilt it back mid-sip. Fits my 25oz tumbler perfectly, and the Java color looks even better in person than on screen.

The OctaLock seal is way more secure than the flimsy lid that came with my old tumbler, and I love that it fits both my 15oz and 25oz bottles so I only need one spare. The Java color is a dead-on match for my existing setup, so it looks like it came with the cup.

Lost my original lid on a road trip and grabbed this replacement—the OctaLock threading matches the tumbler perfectly, no wobble or leaks when I toss it in my bag. The Java color is a bit darker in person than the photos, but it actually looks great against the matte finish.
