The package picture is blue, but the item to be delivered is green. This time, I tried buying it on trial, but I tried to clean the PC periphery before using it by car. You can remove the dusts on top. I can not remove dirt etc. After cleaning the roller part of the printer, it was pretty nice and fairly beautiful. It can not be reused, so it may be a waste to use it in a dirty place.
The air duster only dusts, and since the wiping of the wet cloth was also worrisome because there was a wiping residue when it dried it is soo so it feels good because it was completely removed when using this.
