On the one hand, the “mouse click” mark is the main shape in the IT world. On the other hand, it is the first choice when someone wants to tell about a problem or order something. So “one-click ... check” to ensure the great service that the company provides, it's a clear message to costumers that they need only one click and the service will be done correctly, and as fast as possible. And here the “checkmark” reflects the previous words.
We work with the golden ratio and a specific distance between elements to make the final shape as professional as it should be.
