（会員限定）CAST ウォータージャグ 750ml/1.2L シリコーンパッキン

I was worried about leaks with my old jug, but this white silicone ring creates such a tight seal that I can toss it in my bag without a second thought, and it was surprisingly easy to snap into place.

The replacement ring fits both my 750ml and 1.2L jugs perfectly, and the white silicone is pliable enough that snapping it into place took under a minute. Leak-free after a week of daily use, so no complaints here.

I snagged this silicone packing for my 750ml jug and the flexible ring makes it so easy to seat properly. No more fiddling to get the lid sealed—just a quick press and it’s watertight.
