Some times, designs which we think they are very good did not approved by customer .
It depend on their opinion about color, shape, production time and specially total cost.
Normally, a new customer do not want to pay 200 usd for designing fee. They believe that it is too much. But in fact, we must pay more than 200 usd to create a new design
After all, we still proud about our working, even some of our designs did not make money
