T^T First of all, it doesn't seem to make sense...!!! It's a color change in a backpack worth 250,000 won~!! T^T I can't attach a picture T^T There is a clear stain on the back and shoulders..! Because the design was pretty, I went for a walk in coordination with a white anorak, my God~~!! Is this a normal product?? In my 46 years of living, I have bought various backpacks and bags, but this is the first time I have ever had color transfer. What should I do with this?? T^T Please note that it is absolutely not possible if it is not black clothes. T^T ah!!! I don't really know what to say T^T
