The Sticky Microfiber Screen Cleaner is very practical - use the microfiber (printed) side to clean your phone or eye glasses, back side for storing it on the phone. The Sticky Microfiber Screen Cleaner does not contain any adhesive/glue so it will not leave any mark on the phone or similar.
If used correctly, the product is re-usable for many times (daily use over 1 year!). If the pad gets dirty, just wash it with liquid soap, dry it out and use again.
NB! The Sticky Microfiber Screen Cleaner is not suitable storing on silicone case, silicone rejects it.
