Went to slip them on last night and oops too tight. Obviously not of the original pattern but what I need so I don't butcher these ones is the original measurement.
What I have now is -
Rough measuring

Around 110mm

They even look wrong, never took them out of the box they went straight into the cupboard

Internal appears right.

So just need to know how much to trim from the inside part so not as obvious. Going to be fun trimming them !!!
