O-Ring For Solofill V1 Gold, and SoloPod 2.0 2-in-1 100% Silicone Quantity: 2

Too thick for rim..Had to sit in hot water and then close Solofil cup with heavy object on it to conform..will not buy again..

Perfect fit black o-ring for my kcup. Came in the mail earlier than promised ship date.

Perfect fit!

Didn’t fit. Can’t close the lid with newo-ring.

I have used them on two different varieties of reusable K-cups, and they fit perfectly on both.
