I am trying to find the difference (other than price) between these two SKU's. As far as I can tell, the more expensive ones seem coated possibly and that's what I have purchased in the past.
Pelican only sells the one I've been getting but I'm curious about the other just so that I know.

The usual one:

Glyco 94410190100


The alternate that is less money for some reason:
https://www.fcpeuro.com/products/por...68-05543009291
Glyco 05543009291

951and944S

944.101.901.00 fits all 944/968 standard.

Only other ones I knew of was the .25mm oversized and those are a 928 part number.
