On screen control Panels with open airflow.
These have a clear protectant layer on the wattage buttons to avoid damage (if end user want's to they can sand down the layer)
I am not a professional at making panels. I am doing this all from home, hand polishing, sanding. And I do all of my own QC. Imperfections are to be found (very minor usually)
Any issues please don't be afraid to give constructive criticism
