Shop Redheart.com site:
"These hooks have the broadest size range within the Susan Bates family of hooks. Made of lightweight aluminum; each Silvalume hook undergoes a special anodizing process that etches away all surface impurities. In addition; each hook is heat treated for strength and durability and polished for a velvety smooth finish. Each size is color coded so you can find the size you need at a glance. Our famous in line head helps reduce wrist motion for fatigue free crocheting and helps you maintain a more consistent gauge."
The set already comes with this vinyl case. As you can see, one set includes the following sizes: US F5, G6, H8, I9, J10, and K10.5 (3.75mm, 4mm, 5mm, 5.5mm, 6mm, 6.5mm). If you're curious about conversions, go to this link to check the different crochet hook sizes.
