Corner bumpers you can easily reduce the risk of your child getting hurt on the sharp corners of tables and cabinets. In order to achieve optimal adhesion the corner bumper should be left with no weight on for at least 24 hours. Clean the surfaces with denatured methylated spirit/window cleaner before fixing the tape. Do not use cleaning agents containing oil or soap. The tape can only be used on smooth surfaces such as painted or lacquered wood/metal and glass, or foiled particleboard. Package List: Corner bumper 8 pack
