i can roll pretty well but still some small pieces fall out the sides while rolling so i put them back in the baggy i just bought a roller and now i have no problems with stuff falling out and the joints look perfect everytime i never used cardboard roaches though never really felt the need too

you can get a small roller for $3-5 or a long one For $8-15
even with a roller its still good to know how to roll a joint by hand so keep at it
