Opinions regarding dog tags being turned into ID bracelets

[tthen]

I suspect this is speculative regarding when and for what. Were individual tags crafted into ID bracelets for servicemen while in the service or more likely for post service or sweetheart use? Here is an example.

Would love to hear your thoughts.

Very common occurrence to have modified for wrist wear in both WWI and WWII.
