防漏吸管蓋，紅色

I’ve been using this red lid on my 500ml bottle and it really doesn’t leak, even when tossed in my bag. The plastic feels solid and the spout design is easy to sip from without spilling.

Finally, a lid that actually stays shut in my bag—the sturdy plastic feels solid and the spout hasn't leaked a drop in two weeks of daily use. It snaps onto my 500ml bottle with a satisfying click and makes sipping water one-handed while walking way easier than I expected.

The plastic feels sturdy enough for daily tossing in my bag, and the spout seal does its job on the 300ml bottle without any leaks so far. Only gripe is it's a bit stiff to snap on at first, but that should loosen up with use.
