Writer left out correcting fluid having erased last name (4-3,3)

'writer' is the definition.
(I've seen this before)

'left out correcting fluid having erased last name' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'correcting fluid' becomes 'Tippex'.
'having erased last' means to remove the last letter (the last letter is erased).
'name' becomes 'n' (common abbreviation e.g. on forms).
'tippex' with its final letter taken away is 'tippe'.
'left' is an anagram of 'felt'.
'felt'+'tippe'+'n'='FELT-TIP PEN'
