Yes, yes it is! And as I pointed out in that other post you can now get fake plastic copy ones for less than a fiver (they won’t last long and will pinch you once they break but what do you want for that litte? Or you can get some amazing metal ones from sites like Toys for Naughty Boys for about £30, which is great value if you ask me.
Check out the chastity device reviews on KeepHimCaged, they’re usually pretty helpful.
