Realigned my spine
After years of carrying a bulky wallet in my back pocket I opted for the MK Wallet. It is perfect for reducing the clutter of your wallet down to bare essentials. My back feeling better was an unexpected joy as well.
I do not know if it will become an issue but the clip side of the wallet is not fixed in place. Perhaps this is the way it is meant to be but it is the only thing I do not love about this wallet.
