"For inside the present lay The Combs – the set of combs, side and back, that
Della had stared at and longed for so long in a Broadway window. The beautiful
combs were made of pure tortoise shell with jewelled rims – just the right color
to wear in her beautiful hair that was now gone. They were expensive combs, she
knew, and although she had loved the combs, she never thought that she might
actually own them. And now that they were hers, the beautiful hair that should
have needed the combs was gone."
What type of irony is shown in this passage?
