Yes, the "s" version is a snug fit and gives a nice tight reminder where all your bits and pieces are. I'd recommend one of the "Kept for Her" KSD-G3accessories to help prevent withdrawal if that level of extra security is important. Last time I tried to find a proper keyholder I ended up paying a relatively small sum to a Mistress who just kept the money and gave the excuse of being "too busy". Once bitten, twice shy. One of a number of unhappy experiences I'm afraid to say. Ho hum.
