I don't see the point of this. But that's probably the whole point of it all. Some tings needs to be done for the sake of coolness. €23 isn't a huge amount and you are at least going to have an idea about the temperature of the environment and the way it reacts to touch is super awesome
Take a look at that and look me in the eye and tell me you won't love it. It's a great wallet to carry to impress and you can carry 8 cards in it. Cool Hunt!!
