I have the Mono Koala Wallet and love it. I only own one other wallet a Black Epi PTI and I rarely change from using my Koala I find it to be the perfect wallet: the right size, enough cc slots, generous cash capacity, perfect amount of brass with the koala clip closure! Love it.
I have it in Mono and not too crazy about it ... aside from not being able to use the zipped pocket for coins, it also gets too bulky when it's full of cc's and cash/receipts. Maybe I just carry too much stuff ... I prefer the Alexandra which is a little similar.
I find it a bit on the bulky side when filled. I use a Cles for coins. I do like the buckle though. I had to have mine repaired though. Hardly used (since I switch alot) but the glazing on the fold peeled. Were I to do it all over again, I would get the Alexandra (which wasn't out when I got mine.)
I have a red epi Koala. The only problem I have with it is sometimes it is hard for me to unclasp it. It has the pointy clasp, not the round one. I love this wallet, however, and use it daily and have been doing so for over a year. It looks brand new and the silver hardware is still shining bright!
I have one in the vernis pomme d'amour and I love it!
It's really one of the best wallets I've had so far, no problem with the coin compartment though. Maybe cos my currency has small coins.
And after 1 year, it's still in great condition, except the hardware tends to have a little scratches.
If I had to buy a new wallet if this one finally wears out (whenever that'll be), I'll probably get another koala!
