Hi , this Kyle from China. Since a month ago, my team wanted to build a brand to produce the high quality of mechanical keyboard and headset to sell aboard. Now we already got the license to do so, and we can't wait to bring our products to meet everyone. But the products are still in the period of designing, it would take some time :( There are some questions we can't find the ways to solve - how to sell keyboard on Drop, and the details about how Drop charge per product? - Actually I sent an email to Drop Studio for some questions, but I didn't receive the answer.( Drop Studio also mentioned that they can contact me only if they were interested in my design / products ). So I'm here ask for help. If anyone can answer my question, I would really appreciate it :)
