プレイタンブラー 300ml/480ml シリコーンパッキン

Exactly the same shape and size as the original, so the lid seals perfectly again—no more leaks in my diaper bag. I’m just relieved to have found the right replacement part without buying a whole new cup.

Finally found a replacement that actually seals properly again, my toddler's tumbler hasn't leaked a drop since I swapped the old one out. The silicone feels just as flexible as the original, so it's been a perfect fit for the lid.

The replacement packing fits my tumbler perfectly, and the silicone feels even more flexible than the original, which makes cleaning a breeze. I'm glad I found this part instead of buying a whole new cup.
