Ordered this set because the old silicone on my mug was starting to get grimy, and it popped right into place. The seal feels snug enough that I can toss my mug in my bag without worrying about leaks.

Penelope ★★★★★ Oct 21, 2026

Finally found a replacement that fits my old SM-JB mug perfectly — the black color matches the original. It snapped on firmly without any gaps or leaks.

I’ve been using this mouth ring set on my old SM-JA mug for a month now, and it fits perfectly with no leaks—even after being tossed in my bag. The black color matches the original part exactly, so it looks like new. Very glad I found this instead of buying a whole new thermos.
