Dichtungsring Aroma Plus ホワイト

My old one had warped after a few years, so it's nice to get a perfect seal on the lid again for my morning coffee. The silicone is just as firm as the original.

Was a bit skeptical about finding the right fit, but this sealing ring snapped into place perfectly on my old thermos. The white color matches the original part exactly, and the seal is much tighter now—no more leaks in my bag.

The seal fits snugly and instantly stopped the minor leakage I had been dealing with. For a simple rubber ring, it feels well-made and does exactly what it should, though the price is a bit steep for such a small part.
