"Brilliant value icing coupler" star star star star star Brilliant value icing coupler. This fits my 1M and 2D nozzles but DOES NOT FIT lakelands 7 nozzle set - they are too big (brilliant nozzles but too big for this coupler). Top tip - dont overfill the piping bags as it gets too hard to squeeze out!
"Works well when..." star star star star star ...you don't fill the bags too full! I tried putting 500g mix in each, but couldn't control it. Took half out and it worked fab! Works with my random large nozzle too.
