キャップパッキング（ピンク）SM-LB（-PM）フローラルピンク用

The pink color matches my floral mug perfectly, and the gasket seals tightly so there’s no leaking when I toss it in my bag.

I was worried this replacement part wouldn't seal tightly, but it fits the lid perfectly and stays airtight. The rubber has just the right amount of give, and the soft pink hue looks identical to the original.

My old seal was cracked for months and I kept putting off replacing it, but this pink cap packing fits my SM-LB mug like a glove. So relieved to have a tight seal again without any leaks in my bag.
