BONBO ストローカップ 200ml シリコーンパッキン 2個入り

The silicone feels thicker than the original, so the seal is actually snugger now—no leaks even when she tilts it mid-sip. Having two spares means I’m not scrambling when one gets chewed up.

The seal on these replacement packings is noticeably tighter than the old one, and the 200ml cup no longer leaks when my toddler tips it over. They were easy to swap out in about a minute.

The silicone is softer than the original packing that came with our cup, making it easier to snap the lid on tight without leaks. My toddler has been shaking it around and not a drop spills, which is exactly what I needed.
