Brigade Quartermasters sells them online at ActionGear.com. Here's a link to them. http://www.actiongear.com/cgi-bin/tame.e...mEyc0aoDIaWEDow
Bloodstoppers, I'm fairly certain, are the same thing; just a civilian version (i.e. white instead of olive drab and packaged in a more clinical manner). They are available online from a lot of places; just do a web search.
Stay safe,
