จุกทดแทนสำหรับแก้วฝึกหัด Click Lock® Bite Proof Trainer Cups, 2 ชิ้น

The valve really does stop leaks—I tossed one in the diaper bag and not a drop escaped. These are ultra-soft, so my little one actually chews on them without fussing. Wish I’d grabbed these two-packs sooner.

Spent way too long hunting for these and they fit perfectly, the valve keeps the liquid sealed even when the cup gets tossed across the floor. The spout is soft enough that my little one doesn't fight me when I swap them out, which is a win in itself.

My toddler chews through spouts constantly, but these replacement ones are holding up much better than the originals. The ultra-soft silicone is really gentle on her gums, and the built-in valve still prevents any leaks. So glad I found a two-pack for the price.
