Could anyone recommend a collar that would be good for public wear?

I work on a cam site and I was recently approached by a number of potential candidates for slaves. Considering that we are miles/states/countries apart, there are some things we CAN do and some things we CAN'T. One thing that I CAN do is make sure that my slaves remember that they are mine completely, even when they are away from me. So I got the idea that I could have my slaves (sometimes or always, depending on the person and what the relationship/situation is like) wear a collar of ownership, even in public (possibly at work). I was thus wondering if there were any good collars on EF that might look unassuming and/or could be worn on other parts of the body (that could be hidden) so that it is always on their person. These would need to fit men, in this case.

And if not a collar, then what are some good items that could be used to remind a slave of their ownership when they are apart from their mistress? less

Tiny jingle bell anklets or bracelets are always fun if they're not too 'masculine' to agree to wear them, and every time they jingle the guy will be reminded of you. I made my boyfriend one a little while ago and I plan on mailing him it to wear everywhere but work.
you could also do something simple for a 'collar' like a thin black leather choker though. If they're going to be told to wear it at work it's best to make it something plain that most vanilla people wouldn't think twice about.

If you're looking for something really easy to conceal though I'd say try an armband or something that sits up on the bicep so it's hidden from sight under a long sleeve shirt. less

My every day wear collar is a custom made steel collar, which is in the style of the city of Turia in the Gor books. If that is not an option since they can be expensive, I would go for a thin leather collar that can be strapped around the thigh, or a thigh cuff. They are easily concealed. less
