ハンドル付き断熱ストローカップ（グリーンマッシュルーム） 1個

My toddler loves holding it by the handles, and the silicone straw has held up well to all their chewing. It keeps drinks cold for a good while without leaking in the diaper bag.

My 15-month-old figured out the silicone straw in about two days, way faster than the hard spout on his old cup. The handles are chunky enough for his little fists, and the sliding lid actually stays shut when it gets tossed off the high chair. Nothing has leaked in the diaper bag yet.

The mushrooms pattern is adorable, and the insulation actually keeps water cold for hours even when we're outside. My daughter can grip the handles easily, and the sliding lid hasn't leaked once in her diaper bag.
