It has a medium one and a large one and let me tell you if you are not used to the butt plugs that have the large toys, then this not the one for you, you are going to need a smaller one in which they do carry.
I love how smooth this hook feels and just inserts' into my butt with no problem. I had to use the small one before the big one because I was not ready for it. It has been a while since I done anything anal and I had to gauge my butt before I could start. I feared that it was going to be to big but once I started working with it I had no problems with it.
If you decide to get this, be sure to use lots of lube and gauge yourself first because if you do not, it will feel like you are splitting and ripping and it will be a negative experience.
If you have a prostate and enjoy prostate play, this would be great for you because it will rub against it once you are thrusting. This sits in my butt nicely as I am being banged and due to the hook, I do not have to worry about it falling out and in my opinion this is a great thing and gives a very pleasurable experience.
