Truly long spaghetti Something I recall from my childhood, but which I last recall seeing about 45 years ago, is long boxes (about 2 feet long, 5" x 5" in square cross section) of spaghetti pasta with very long noodles inside, each bent in the middle making each piece of uncooked pasta about 4 feet long.  Two of the brands I recall (of which I may be in error) were Salerno and Aligheri.  Recently I have been searching the web to try to find this, but cannot even find a reference.  Does anyone remember this, and does anyone know if this is still available?  If I recall correctly, the boxes also had the infamous "pasta number" on them, either "5" or "8", depending on the box.
I imagine you are thinking of spaghetti curvati (o spaghetti con curva, that is, spaghetti with a bend).

It is a pasta format typical of Southern Italy.

Some brands refer to those as spaghetti lunghi (long spaghetti).

I am not aware of a specific name for them, although I am fairly sure there are names in various Italian dialects.
