Interesting...looking at these I am pretty certain they are made by the same manufacturer that makes Knitter's Pride needles (and formerly knit picks). They have the same size and type of packaging, same size marking stickers. I am positive the cords will be the same flexible cords people are used to with Knitter's Pride and KnitPicks.
The Comfy interchangeable set, hmmm, where have I heard that before? Oh yeah, the Comby sets. The difference being that the Comby is a sampler of 3 needle types and doesn't include the extra 32" cord and end caps.
