For $10 you can purchase a great looking bracelet - made of recycled rubber and metal - and $5 will go to Best Friends Animal Society. The metal is embossed with "I'm Tired Of Animal Cruelty".
If you have a large wrist, definitely get the men's size, as the women's/child size does run small.
I love it! It's much nicer than the rubber "charity" bracelets. And it is proving to be a great conversation starter - people want to read it.
