SE brand saw blades

[zimmerstutzen]

Was given a small envelope marked SE piercing saw blade 4/0    12 packs of 12, pinless and 5.25 inches long. Says made in India. The picture looks like a coping saw or jeweler's saw.

 

They look like scroll saw blades.  Anybody heard/know anything about them?

Here is a link to them on Amazon. Pretty cheap as far as price goes. It looks like they are made for a hand-held saw for doing very fine work.
