Hello,
might try wrap a piece of paper around coil/cotton to help insert
Something thin and strong. a piece of a post it note? not too much paper, not too tight
Slide it in, pull the paper out. might have to hold the coil/cotton in with a pencil or something
pre roll paper to make it want to round
Not sure I have a BF, I know I have still triton rba if you need picture, but should be easy
Don't try to save the wick, it's cheap. Trim or tear as you go, and as you need, same with the paper.
