The Monster Cellphone Screen Cleaner is a super cute and well made screen cleaner. You can safely attach the screen cleaner to the rear of your devices or even your mirror, makeup powder, or any of your items. However, the cleaner does not attach to materials like canvas or a silicone surface. To clean the screen, simply detach the cleaner from your item and wipe your screen with the front of the cleaner. Once the cleaner gets dirty, you can wash it with water and soap and let it dry, then you can reuse it! Please check out the photos to learn more!
