Fountain Pen

Fun to write with 
On Thursday they came
Ultimate Writing Utinsel
Never going to write with anything else
Tempting to use for math
And I do not want to abbreviate
Illuminates a pencil's dull scratch
Never going to write with anything else

Pencils aren't good enough compared to the flow of the fountain pen
Earnest is this poem, I believe every letter
Never going to write with anything else
