So, I was looking at the screen grab, and it looks like the two badges on the left in the back row are on retractable lanyards. Anybody got any leads on what type they may be? I'm gonna head to Staples later and see what they have, but I'd love to try and find out what the actual type used on the show was.
Upon further review of the image, I think I just answered my own question. It also appears that the Blue/Grey one also has this lanyard, which appears to be very similar to this one:
This is made by IDville and has a retractable measuring tape. They appear to only be sold in groups of 25 and are kind of spendy.

Looking at ebay right now, there are similar ones much cheaper. Like just over $1 each. I'll probably go with something like that.
