We have received the sample and I think the black colour is better option for production. The clear colour may be a bit difficult to control the clarity and it is not nice if it is not perfect.
Before we finalise for production, can you let me know what is the part price difference between NYLON and PP for NAX3B. I think PP should be able to do but I think nylon will the best for this application considering that some mats may be hung for quite a long time and nylon will not distort.
