Stopper Gasket for SM-PD20

I'd been worried about leaks since the original gasket wore out, but this replacement sealed the lid perfectly and my morning coffee stayed hot for hours. The silicone feels durable and the installation was straightforward.

My old mug started leaking after a year, so I ordered this stopper gasket and the seal is tight again, no drips even when it’s tossed in my bag. It’s a genuine replacement part that fits the SM-PD series perfectly, and installation took me less than a minute.

The seal on this replacement gasket is nice and tight—my mug hasn’t leaked a drop since I swapped it in after a year of use. It fit perfectly into the lid of my SM-PD20 without any fuss. Definitely worth the price for keeping my old mug going.
