Keep your whiteboards clean and go super green. Instead of shipping litres of water around, 1 pack of 6 sachets can make 3 litres of cleaner. Get started with a Show-me refillable cleaner set, or simply reuse an existing trigger spray bottle. Save plastic, reduce shipping weight, avoid leaks and save space. Easy to use: place a sachet in your bottle, add warm water to the fill line, screw on lid and shake to dissolve.
