NSFW, 1st test with new toys, a simple hogtie, and a little chastity.

No, not them. This came in two parts. A left side and a right side. It was hinged and covered everything, cock and balls,. It would be be closed and locked with a locking pin. No belt, no straps.
I remember seeing in a chastity catalog, I think called medieval steel from the 90s.

Fetters in London.

A number of years ago, there was a steel cock and ball cave. It would encase everything in steel and locks on. No erection can happen and no touching allowed.
I don’t know if anyone is selling these, but I had one eons ago and there was no way oh getting out of it once it’s locked on.

was it a "Seed Pod" by any chance?
a bit like this one.. https://www.secretleather.com/mr-s-leath...-cage.html
but fully enclosed?

this one maybe

   

Yes, a seed pod. That’s what it’s called.
Mine was a round ball type with a small hole and lips to hold it in place with eather a padlock or zip ties.
And if you think a zip tie would be easer to cut off, think again.
