Cốc Rơm Có Trọng Lượng Superstar

My little one figured out the straw in two days flat, and I love that she can tip it upside down without a single drop escaping thanks to that two-piece valve. Tossed it in the diaper bag with zero leaks, which is honestly a first for us.

We’ve tried three other straw cups and this is the first one she can actually tip sideways without a drop hitting her bib. The two-piece valve holds up even when she tosses it out of the stroller. Finally, dry floors on the way to daycare.

My 8-month-old figured this out in two days, and the two-piece valve actually holds up in the diaper bag—not a single leak so far. The any-angle drinking is a lifesaver during car rides when he decides to tip it every which way.
