Engage and delight with this set of four glowing writing surfaces and recharging station. Select a board from the docking station and switch on to a chosen colour. Engage and support reluctant learners, record findings, get creative and see your designs glow. There are seven colour options and an automatic scrolling option. Simply press the button to explore different effects. A four hour charge allows 10-12 hours of continual use. Use with any dry wipe pens but we recommend fluorescent pens for extra effect. Our own TTS brand chalk markers (AR03190) are a great value option. Please note that some chalk markers need pumping before use to draw ink. Simply wipe the boards clean with a damp cloth after use to make them ready to write on again. Supplied with a 5V 1A international adaptor.
