450mL Silicone Lid

Finally, a lid that actually stays on my 450 mug without popping off mid-sip. The silicone is thick enough to create a tight seal, yet easy to remove when I need to refill.

Wasn't sure a lid could make much difference, but this one turned my double-wall mug into something I actually carry around. The silicone flexes just enough to pop on without a fight, and it hasn't leaked in my bag once.

The silicone seals tight enough that I can toss the mug in my bag without worrying about leaks. It's also flexible enough to peel off easily for washing, which I didn't expect from a lid this grippy.
