Pretty Polly Nylons Gloss Tights

is it really £18 for one pair of tights?

What denier stocking / hold ups are these ? Thanks :)

Do these tights have a sheer toe?

The main page says pack of 3 but once I add these tights to my basket it says 1. I see in one of the reviews only 1 pair was sent. How many in a pack?
