Top tops 😁
These do exactly what you’d expect. Needed to replace the seals in my thermal mugs but wasn’t convinced about the valve fitting in one so went for the whole lid. Looks odd having a colour mismatch didn’t have mine in stock, but what does that matter?? New life to old mugs👍

Spare lid
Not the same colour as my cup, but it fits although it's only spare at the moment, should I lose any part of the original. It's so helpful being able to get replacements.
