About the product Our sponge contains PET. It can better resist the strongest impact than ordinary mirrors, significantly reducing the risk of shattering or damage. Its usage is simple: clean the dust or debris on the glass surface, open the lid, wipe the sponge on the glass surface, wipe gently, wait 5-10 minutes and then wipe it clean with a dry cloth. After use, looking from the outside of the glass, you can't see the indoor situation clearly, causing a one-way glass effect.
