I've been trying to communicate with drop, but I don't understand why it was delayed. Maybe it's because of the environment, but it finally came. In addition, I designed a lot of products before, so I have been busy solving the production problems. At present, it seems that they are getting better. The problem of "plastic" is very complicated, but the situation is that it has been completed and is waiting for transportation. The users in China have already got the production And the effect is very good. I'm very sorry for the lack of communication before. Obviously, this is my effort to express with the help of translation software.

In addition, the resin key has been modified for 4 times and has been adjusted to a very comfortable transmittance, and the upper and lower brightness will be different due to different lamp positions.
