Hello, I seem to have encountered your problem before. The following are my original solutions and methods. I hope I can help you. Please forgive me if there is any mistake! Japanese medicine box company developed onaka thin belly products on 20 15. 20 16 officially began to sell in various physical stores in Japan. Later, after purchasing and agency, it gradually sold well in China. Onaka incremental version will be launched in 2020. Thank you very much for your patience. If it helps, please adopt it. Wish you a happy life! thank you
