Duct tape is one of the most versatile adhesive materials known today. From fixing the bumper of your car that keeps falling off, to creating a sturdy wallet. From alternative wrapping to sticking a friend to the wall, Duct tape is there. And it will stay there. It will stick to anything and hold for a very darn long time too! The cloth-backed tape was invented some time during World War II, and also proved itself useful as a base material for lettering. VLNL Duct was originally designed by DBXL as a logo for temporary Amsterdam restaurant BAUT. DBXL imagined an owner taping the name on the window of his shop using Duct tape. The font was used for all communication of the restaurant. Duct is a sturdy, rough all-caps typeface that will stick to anything.
