I used a couple of icons from FlatIcon every day. My company doesn't let me have any graphics programs because of the cost and it really is a lifesaver. Even though I understand they want to save money and have "simple" marketing pieces, having a resource that is free is huge for me. The flexibility of the icons is awesome and they import without a white background (bless you wonderful people!) FlatIcon saves me so much grief. I'm actually hoping to convince the company on the new software review to upgrade to premium! (Below is a sample of an email I'm making with our company values. I am able to edit the icons to use our company colors! Tell me that isn't AMAZING! Oh that's right - you can't!)
