paste the value text only of a cell that has text prefix format?

[leecavturbo]

I have a cell with prefix "item "@
when I enter a value eg 102 the cell displays item 102.
how can I copy that full string without macro and paste to other cell?

or a format that will insert the whole string as a value? probably complicated as would have to enter number then the cell refresh add the prefix and then re insert the full string as a value ?

how about a custom cell format of

"item @ "###

then just add your number
