ZZ_UPennThread options will match as closely to the leather as possible. What specific combo are you looking for?
For buckles, it is only going to be the stainless steel pictured.
GuardedGoodsThanks. I am happy with Horween black and the default buckle. Hopefully you can add more buckle options next time. BTW, what are the differences of various black options? Do they have different colors on the reverse side?
