Safety first: The thickened anti-collision angle protector prevents us from getting injured at tables, furniture, and sharp corners.Simple installation: All required parts, adding additional solving adhesive, were pre applied at the factory. You simply need to tear off the cover, stick it at the nook of the table, and press for one minute! It's that simple! (There is also a spare stable adhesive in the packaging.)Suitable for correct angles on tables, but now not for rounded corners. Clean the outside before installation to ensure there's no dust, water, or oil. Do no longer stream the nook protector within 24 hours after installation.
