Looks good. I like how the tab that holds the chain for the closure also holds the key clip ring.
So, you found and used the post closure . . . how easy is it to fit and use? I've thought of using one, but don't know if it would be difficult to attach in creation or for day-to-day usage. It should be secure (as long as you avoid headstands, not a good idea kilted anyways). Where did you get your's? How was the customer service/price/quality balance?

For Ron's behalf:
What was the dimensions in inches (or metric if that is what you use, though most of us Americans don't have any idea of what that would mean)?

Looks good and will look good on ya!
