'felt pen' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'thanks former model in' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'former' becomes 'ex' (prefix meaning former or onetime).
'model' becomes 'T' (Ford Model T car).
'in' indicates putting letters inside.
'ex'+'t'='ext'
'ta' enclosing 'ext' is 'TEXTA'.
