Got the samples. The plates are made of aluminium and are extremely light and bendable, like extremely. To make it suitable to send, i will have to add two layers of cardboard to but the plate(s) and PCBs between.
This will cost me much in shipping, as the orders are now, this will work out fine. It also helps that the plate weigh like 30g or something along those lines. If someone has some tips for packaging(i am not an expert at all) or want to cancel they order because of the freight, please feel free to do so.
Blue
Red
Bent(easy to fix, but conserning because of the massive bubblewrap they came in)
Close up
Red vs blue
