Mature Metal Punishment Pins

I was thinking about getting these pins installed in my jailbird and wanted to know if anyone has tried them? I’m just curious what size and type of pins people typically use. How do they hold up for long-term wear? Also, are they uncomfortable or painful when you aren’t erect? Any feedback or advice would be much appreciated.

We have the punishment pins for my jailbird. I own a small blunt, a medium blunt, and a medium crosshatch. Can they be worn long term? As long as there's no teasing or erections, I can wear the medium one without feeling it much. With the small pin, I can even tolerate some teasing and partial erections. That seems to be about all my jailbird allows. The longest I've kept a punishment pin in was 1 week. When they removed mine, there was a nice bruise on top of the shaft where the pin touched the skin. For the medium pins, I usually only manage a day or two; last time we used the medium crosshatch, my skin broke and formed a scab over the bleeding spot. To sum up, I can use the small pin with no real problems since I have a tight-fitting cage. The medium ones are true to their name as punishment pins, so we only put them in when I'm in some kind of trouble.
