Hi there,
We have lots of cages but we have two that are our favourites at the moment. They are both from Toys4NaughtyBoys – The Arc:

(we take out the insert)
and The Tight Squeeze.

They are both super comfortable, hubby can wear the indefinitely now he’s got used to it, and I think they both look really hot, which is important too.
We have been sent some more to review though we’ll let you know how we get on with them
