Review on Ultimate Titanium KeySmart: A Must-Have Organizer for Men's Accessories by Mark Meyer

In no case will it contain the 8 default keys. With the fiber washers included between each key (makes it easier to turn individually), I was only able to fit 6 keys in. Well 5 plus a small key ring adapter so basically 6. If the keys are thinner than standard household keys you can get 8 of them. So if you need more than 6 keys, buy an expansion kit. Otherwise, it keeps my keys neatly in my pocket.
