Description The Hydro Pencil allows you to change the note without changing the label. It's fun at your fingertips. Paired with Write-On Labels, this pencil gives you the opportunity to organize at home or to include a smiley face in your child's lunchbox or notebook. Simply wipe off the message with a clean cloth to begin again. How To Use For Best Results: Sharpen Pull the string near the tip to split the wrapper. Peel just enough to expose more wax. Sharpen with a manual pencil or crayon sharpener. Do not use an electric sharpener. Write Make sure the label is clean and dry. Use light pressure to limit wax buildup. Erase Wipe with a wet cloth and warm, soapy water. Some shadowing may remain over time. To minimize residue, clean soon after use rather than leaving writing overnight.
