12 mm crochet hook
A 12 mm crochet hook has no US letter or number in the Craft Yarn Council chart; it is sold by its millimeter size.
It is in the recommended hook range for 6 Super Bulky yarn (Super bulky, roving). Amigurumi often uses a hook a size or two smaller than the label says, for a tight fabric.
