Original He-Man Power Sword strap - help identify this material!
 

I'm currently working on restoring an original Power Sword. It came without the full strap, but a small amount was left inside the hilt. It's a black, flexible, glossy, 1/4" vinyl (or other flexible plastic material). One side has vertical ridges; the other side is plain.

Can anyone help identify this material so I can track it down? Alternately, if you can think of a good replacement material, that's appreciated as well.

Thanks y'all!

Back in the day, the common Halloween pails I remember had a flat, ridged vinyl strap riveted in with brass as a handle. I would think that'd be similar.

Awesome! Do you know where I can track that down?

Just looking on ebay, I see some with a flat vinyl strap searching "vintage halloween pail" but noting with quite the ribbed texture I remember. For your purposes, not sure how important that is anyway.

Thank you so much!
