These are my favorites knitting needles.
The set is from Knitters Pride "Dreamz" circulars interchangeable made of laminated birch, they are great. Each size is color coded from 3.5mm to 6.0mm or US 4 to 10.
with cords from 40cm/16" up to 150cm/60" plus connectors that can even make any lenght I really need.
The other 2 metallic ones on top are my favorites for socks knitting, they are fix circulars Addi Turbo, the best ever needles, quite expensive but they really worth it.
