Hi Angela.
I bought my bracelets from an oranization called Choose Hope. They can be found at choosehope.com. If you buy 100 or more they only charge $1.00 US. Less then that they are $2.00. The saying on their bracelets is SAY IT – FIGHT IT – CURE IT. They also have many other items.
Green is the color for liver on the website. It was the closet color for me since they removed 70% of my liver, the common bile trunk and gallbladder.
Some websites will say yellow is for liver but yellow is the most common color for many organizations and not ones dealing with cancer. I wanted a unique color so when people ask what does that bracelet represent, it starts a conversation.
Hope this helps. I don’t support/advertise for any single organization. This is just where I found the items I was looking for.
