I ordered the set of 8" -20cm Karbonz double pointed needles based on the sizes in the write up about them. It says there are 5 sets starting from 2mm to 4mm. What I actually received was 2.5 mm up to 5mm needles but the good thing is that there are 6 sets. I was looking for the smaller sized needle which is why I bought the set. The needles are very nice and smooth at the tips although I found I had to get used to how the yarn slides down to the change from metal to karbonz. They seem really sturdy and I expect I will get use out of the ones I received. I'll be looking for a 2 and 2.25 needles to complete the set as those are the ones I'll use the most
