How do these work in regards to number and letter. I have a few that I've got with magazines, sets etc. I normally use a 9MM nozzle, lately I can't see to make my buttercream neat. I get peed off with it because I know I can do better. I HATE plastic nozzles, BC doesnt seem to be as sharp with plastic.
What do people tend to use on a regular basis or which would you recommend for a nice rose type swirl effect?
