This is the fourth such Rolf's keycase I have owned over about 20+ years.  The illustration on Amazon shows a different, newer type of key hook, but I am glad Belt Outlet sent me the old model.  I like the easy-release key feature and the size, even though I now carry only four keys.  One of my keys is a fat Lexus transmitter key, but it fits easily in this case.  The case itself is thin, but well-constructed of good leather.  Many of the other brands give you a wallet and card case along with the key case, but I just want a key case!  I already have a wallet.  And I have never worn out a clasp on this model, after thousands of openings and closings.
After 6-7 years, the leather gradually wears away at the edges, requiring the purchase of a new one.
