The symbols in our database are not for sale. However, you can trademark your logo. The combination of the symbol, color, name of your company, and typeface all make an original logo.
Once you make an original logo and purchase the high resolution files, the logo belongs to you. Since you created it, it is unique to you. The elements you choose to use are a part of our database, but you make the logo uniquely your own by designing the layout, colors, text, effects, etc.
We would NOT take your logo as you created it and make it available for sale to anyone. In this case, if you were to purchase the logo, you would be able to go in immediately, make the changes to your logo, and then immediately download the high-resolution versions of your logo.
