Well the closures on my chain are about as good as the chain that came with the sporran so I hope abrasion will not be a major problem. I am considering putting a leather backing on it if I can get it to look good. I'm not worried about oxidation, I don't believe the bright aluminum rings oxidize like the galvanized. (but I've been doing chainmaille for 2 weeks...what do I know? )



~edit~
but I did just finish my first custom job...too bad it was for free...so I'm still an amateur.
