ChiaoGooTwist Shorties Stainless Steel Interchangeable Set, 3-inch (8cm) Large (7230-L)

What size cord goes with this set, can i use the regular cord with these?

Is there a way to make 16" circulars with this set? (Is there a 10" cable available separately? I don't see that anywhere.

I heard that model 7230 is fake is this true?

Are there other size cords that can also be used eith this set?
