吸管蓋濾芯轉接頭

Finally, a way to use my Adventure Purifier without holding the bottle the whole time. The adapter snaps on firmly and the seal is perfect—no leaks when I toss it in my bag.

I was worried the adapter wouldn't seal properly, but it clicks onto the straw lid and holds the purifier tight with zero wobble. Been using it on every hike for a month now and no leaks yet.

Snapped right onto my straw lid and the purifier threaded on without any wobble, which surprised me for such a tiny piece. It also fits the silicone straw tip that came with my straw, so I can switch between setups depending on the trip. Solid little adapter.
