2 Tip protectors used for birth control? Anyway this looks to be a very thin cable. It may work but I don't really trust it. Amazon sells a house-brand cable [amazon.com]
for $5.49 which is much more substantial than this one, but also much more expensive. I bought one and it seems to be high quality. I also bought one of these cheapo cables and it looks like trash. With that said, I haven't tried this one out!
