（会員限定）トゥーゴーボトル 360ml / 480ml シリコーンパッキン 2個入り

Picked up these for my 480ml bottle after misplacing the original seal, and the silicone feels just as snug. They keep everything leak-free in my bag so far, and the subtle gray blends in nicely with the lid.

The gray rings fit my 360ml bottle perfectly and the seal is noticeably tighter than the original one I’d worn out. I grabbed this 2-pack thinking I’d lose one, but the thickness feels reassuringly durable.

Finally, a spare silicone ring that actually fits snugly without that annoying air bubble gap. The 70 mm diameter matches perfectly with my 480 ml bottle’s lid groove.
