Awesome Metta Catharina shoes and leather goods!
I noticed that you've used Saphir leather balm on your Russian reindeer leather. Does it alter the scent of the leather at all? My only experience with this leather is in the form of a watch strap I recently commissioned. My favorite aspect of the leather was unexpectedly its great smell, which I hope would not be suppressed down the road when the leather needs to be conditioned.
