Both of them were available in my preferred colour of black and in pocket size.
I wanted something to replace my Finsbury Pocket in blue, which I use as my daily carry around Filofax/Wallet that you will have heard so much about earlier this year! This size has been working well for me... hard working in fact.
The only downfall I've found with the Finsbury in this mode is that is only has two card pockets and with the pen loop on the right next to the zip pocket it tends to get in the way when I'm trying to retrieve coins from the pocket. The Chameleon solves both of these issues, minor though they might be.
The left inside cover has 5 card slots, which is about the number of cards I have to carry here in France. Like the Finsbury there is a vertical pocket as well behind the card pockets, which will be able to take my UK passport and UK driving licence.
The pen loop is also on this side, which frees up the zip pocket on the back cover for my Euro coins. The pen loop is a nice tight snug fit for my Filofax mini barley pen with no chance at the moment of it slipping out, which has happened a couple of times with the Finsbury. The pen loop is leather, but it has an elasticated part to it as well.
Additionally there is a full width back pocket, which I use for Euro notes, not that I carry much cash!
The Chameleon like the Malden is a full leather organiser, interior and exterior, so it should stand up to the day to day use it will get better than the Finsbury. The leather is lovely and soft and not stiff at all. As you can see in the pictures above it lays fairly flat from new. By choosing the black there isn't the 'two-tone' effect that there is with the other colours in this model.
Personally I like the way that the leather edging has been finished off on the Chameleon better than the Malden. The additional card slots also swayed me towards the Chameleon as well.
As you can see I've not moved over to the Chameleon as yet, I will start the 'move' this weekend, I want to also go through the current contents of my Finsbury and have a bit of a tidy up at the same time! The ring size on the Chameleon is slightly smaller than the Finsbury and Malden (15mm compared to 19mm) so I need to slim the contents down a little.
As usual click on any of the photos to see them full size.
