About the product Our reflective one-way mirror spray contains aluminum powder, acrylic resin, and ultraviolet absorber. It can effectively clean the glass and form an invisible and lasting protective layer on the glass surface to better protect personal privacy. Its usage is very simple: wipe the glass clean, dry it, take an appropriate amount of this product and spray it evenly on the glass, wait for 3-5 minutes to make it semi-dry, and wipe the glass clean with a dry towel. It can improve privacy and achieve one-way visibility, allowing you to occasionally see what is happening outside while preventing others from snooping.
