Female header pack configurations: 2x40-pin and 5x10-pin

Customer:

I’m confused about the configuration of these female headers. Are the 2x40-pin headers actually 2x20 or 1x40? Does the “2x” mean two separate headers are being sold? I have the same question about the 5x10-pin headers. Are there other 2x20 and 2x5 female header options available?

The headers at the 2x40-pin link are 2 separate headers, each 40 pins in length. The headers at the 5x10-pin link come as 5 separate headers, each 10 pins in length.
