PURE 飲用杯 0.5L 用密封環

After a year of daily use my old seal finally gave out — these new ones fit perfectly and my coffee stays hot for hours again. The silicone feels just as sturdy as the original.

Snapped right onto my 0.5 l mug and the lid seals tight again, no leaks when I tip it sideways in my bag. Genuine replacement part, not some loose generic ring, so it fits the groove exactly like the original did.

After my old ring got stiff and started leaking, these spares sealed the lid tight again. They sit snugly in the groove and don't smell rubbery. Glad I grabbed a set instead of replacing the whole mug.
