Echoing what the other reviews have said, I only purchased the duo bags and coupler as I thought my nozzles would fit. When they wouldn't I looked for nozzles on Lakeland site only to find the only thing I could buy was the full kit. So now, I'm stuck with things I cannot use as I don't want to buy a kit which mostly contains things I have already bought. It should be made clearer when purchasing. Though, once sorted and using the right nozzles, it'll be a nifty little gadget.
A note from the team
We're sorry to hear you've been disappointed with this product. The packaging on both the coupler set and small and large duo colour icing bags does state they're to be used with the duo colour icing kit. The kit contains the necessary nozzles to fit the bags as customers own version of nozzles may not fit. We can see you've placed an order for the kit so we hope this will soon get you started.
