If those are 25 yard spools, 8 spools should be enough for about 60 sets.
They are fluorocarbon. The other key piece of information a person might want is the diameter of each one. In the close-up pic you can see that one is .022, the other is .024. Don't know about the rest.
A quick check of Amazon brought up a chart of Seagur Blue sizes:
60 - .029
50 - .026
40 - .024
30 - .022
And Seagur Premier:
60 - .028
40 - .022
30 - .018
With that info (fluorocarbon and the diameter), you could compare this string to any brand name string that publishes their string diameters.
Some relevant info
in this thread.
I think a lot of string makers list the same strings for soprano, concert and tenor. But, some have individual sets. (which make sense, especially for tenor) For example,
Strings by Mail lists Fremont Black tenor strings as .023, .027, .031, and .025.
A little digging should give anyone the insight that they need to know whether or not this stuff will work for them. Looks like they'd be on the "light tension" side for a tenor. You could rearrange things and get a spool of of Premier 80 (.031) if you wanted higher tension.
