How do you include static text in select statement in Dynamic pl/sql

Question

I want to include some atatic text and get the output of 4 columns joined with a ":" delimiter within them in a select statement built using Dynamic PL/SQL. How do I build it.
e.g.
Normal select statement would be
select 'MY SKU IS : ', col1||':'||col2||':'||col3||':'||col4 from table1 where ....where condition
and output looks like :
MY SKU IS A:B:C:D
MY SKU IS a:b:c:d
Dynamically I have -
SQL_Stmt := 'select 'MY SKU IS : ', col1||':'||col2||':'||col3||':'||col4 from table1 where '|| wherecondition;
I understand that this does not work because the single quote terminates the string. But my question is how do I achieve the same result with dynamic PL/SQL ? How do I include the static strings and the delimiters. I have tried using double quote, '\'....
????

                                     col3 || '':'' ||

             ' from table1 where ' || wherecondition;
