The Spellbound Fleshlight sleeve is made up from a single chamber. This chamber runs the entire length of the sleeve.While there is only a single chamber in this sleeve the texture and tightness of the sleeve slightly various three times.
It is fair to say that the three textures you encounter in this sleeve are very similar. What really stands out is how realistic this sleeve feels from start to finish.
If you can imagine this sleeve is divided into three equal sections. I found the widest part was the first section of this sleeve.
The second section is the tightest with the third section being ever so slightly tighter than the first.
