This key fob has aged beautifully! I am so glad I went with the Natural Leather color choice because it has the most patina potential! The construction has held up very well and it has been through some adventures: Italy, hiking through snow, moving... The only care the fob has received has been two separate applications of Blackthorn's Leather Balm for conditioning and water resistance purposes. The brass hardware was an excellent choice and I have had no problems with rusting or the button unsnapping from my belt. The key clip has held my keys, or whatever else I have hung there, without issue. I am glad that Andy did not go with cheap hardware because that is where most fobs seem to fail. The leather can be the best in the world but if it is paired with poor metal it is pretty much useless afterawhile.
In about six months, the leather has darkened and has taken on indigo from my raw denim jeans. While it has gotten more supple and soft, it has not lost any strength and is still as tough as ever. The well burnished edges have not produced any fraying issues and if it wasn't for the patina, you'd probably think I never used this thing!
With many store bought key fobs, the leather (or leather substitute) seems to disintegrate and tear, most likely while you're out and about, and just like that your keys are lost! Not so with my Blackthorn Leather Key Fob. It has been a staple in my EDC and will probably be for a long time.
