I am smitten over their Domed Bronzer Brush. Super dense. Never sheds. Incredibly soft. Totally affordable. I got mine for under $10 and now after using it, I would have easily paid 3 times as much seeing how flawless it applies the powder. And did I mention - it NEVER sheds!!
And all their brushes are environmentally friendly, 100% Cruelty-Free, 100% vegan, made of bamboo + recycled aluminum. They have an entire line of beauty products not just brushes; eyelashes, bath products, cosmetic bags. Make sure to check out their 6 piece starter kit for $12.99 that was awarded one of 'In Style's' 2013 Best Beauty Buys.
You can find Ecotools at Target, Walmart, Amazon, Drugstore.com among other places.
