When we are doing colourfastness on items like doorstops we need to test the base fabric rather than the designs, because it is the fabric on the base that will be coming into contact with the floor.
Can you please make sure that it states which bit to test when requesting tests, it will just help keep costs down and hopefully stop the confusion we have had with the kids doorstops.
我们有寄成品去检测，请帮我看看是什么意思？
