i have this collar i wear it often as possible all day around the house even doing household chores . It is really comfortable and Master loves me wearing it.
I bought this one for I bought this one for my boyfriend. I find it so sexy when he wears it and he finds it quite comfortable during prolonged wearing which makes it a very good buy.
This is an excellent product. It is easy to insert, though there is some initial pain. I can comfortably wear it all day during many different activities.
