طقم السدادة (أسود) لـ SM-RB75E (-XA) ستانلس ستيل، (-BA) أسود

The black stopper matches my mug's finish flawlessly, and it snaps on securely without any wobble. I like that it's a genuine replacement part, not a flimsy knockoff.

Fits perfectly on my SM-RB75E and the black finish matches the mug's body without looking off. Only gripe is the rubber gasket feels a bit stiff when you first twist it into place, but it seals fine after a couple of uses.

Had to replace the stopper on my SM-RB75E after the old one got worn out, and this black set fits perfectly with no leaking so far. Slightly pricey for what's essentially a few small parts, but it solved the problem and the finish blends right in.
