BONBO ストローマグ ストロー 2本入り

I was worried these might not fit snugly, but they click right into the mug with no leaks. The straws are a bit shorter than I expected, which actually works better for my toddler.

The polypropylene feels sturdy enough to survive my kid's constant biting, and having two in the pack means I always have a backup when one inevitably gets lost at daycare. Fits the mug perfectly and cleans up without any weird smells.

My toddler chewed through the original straw in a week, and these replacements fit the mug perfectly, saving me from having to buy a whole new cup. The polypropylene is rigid enough that she can't easily bite it flat.
