Futura™保溫瓶瓶蓋墊圈

My old gasket had gone stiff and was leaking everywhere, but this replacement slipped right into the FUTURA cap with no fuss. The transparent silicone feels just as flexible as the original, so my bottle's back in daily rotation without a single spill.

The transparent material makes it easy to see when it’s getting grimy, which I appreciate for a gasket. It slipped right into my existing cap without any fiddling, so my bottle’s back to leak-free duty.

My old gasket finally gave out, but this replacement fits the FUTURA cap perfectly and the transparent material lets me see that it's seated right. The seal is nice and tight again with no leaks after a week of use.
