Word stickers are 6.5cm on the longest side. Trees and stars range in size from 3cm-1cm - (Trees & Stars are peel & stick) INSTRUCTIONS FOR APPLICATION (word stickers only): Clean the surface that the label is to be applied to with warm soapy water and dry thoroughly. Peel off the back white/blue sheet carefully. You will be left with a carrier sheet (clear) and the label. Carefully align the label to the surface and press down. Ensure you place it correctly as you will not be able to remove and reposition it. Rub over to make sure it has adhered, then simply pull the carrier sheet off slowly. ABOUT THE LABELS: Labels are made from permanent vinyl and are WATER-RESISTANT. We do not recommend use in a dishwasher. Items should be hand washed and dried by gently dabbing with a towel or leaving to air dry. Labels will NOT adhere to textured surfaces.
