I picked these up at the SOS; has anyone seen an NSKK armband before like this one?

That's an unusual armband. Haven't seen it before.

never seen one.. Is it embroidered? or looks like its stitched...... Were they together as one group?

The lettering is stitched; I ran a black light on it, and there was no glow. I bought the pieces separate at the SOS.
