The sticky mat consists of 30 thin plastic sheets coated with glue. The glue effectively traps all the dirt and dust from passing shoes and trolleys. When the sheet is filled with dirt, you just tear it off and throw it away. The sheets are numbered so that you know in good time when they are running out. The mat is suitable for environments where there is a lot of dirt and dust and where you want to keep clean and tidy around e.g. entrances, passages and corridors. The adhesive mat is delivered in a package of 4 blocks containing 30 sheets each.
