BONBO スナックボウル シリコーンパッキン 2個入り

The 80mm diameter rings fit my snack bowl perfectly; they snap into place easily and feel sturdy. The seal is noticeably tighter now, so no more leaks in my toddler's lunch bag. Finally, a simple fix that actually works.

Hard to believe those tiny silicone rings make such a difference—our kid’s snack bowl now seals perfectly every time, no more leaks in the lunch bag.

Exactly the right size to fit our snack bowl, and the seal feels tighter than the original one we'd worn down. My toddler hasn't managed to pry it open since we swapped these in.
