What is exactly the difference between all the different croc treatments from Bottega? I'm in the market for a croc wallet, but I can't decide if I should go for something in cocco lave or crocodile fume...or even the new tie-dye! Any suggestions? I'd love to hear about how the crocs will age as a wallet (bifold) as well, if anyone can share their experience. For durability in exotics, should I stay with my reptile or go for a birdie?
