T2 X Qwetch Lid

The lid fits my flask perfectly and the seal keeps everything leak-free even when I toss it in my bag. I love that it’s from a B-Corp collaboration, feels good to support sustainable design.

I've been using this lid for a few weeks now and the seal is incredibly tight—not a single drop has escaped in my bag. The french design feels substantial and well-made, which gives me confidence it'll last.

Finally found a lid that doesn’t leak in my bag—the seal is firm and the threading lines up perfectly every time. I’ve been using it daily for a week and it’s held up great through hot and cold drinks.
