Have fun using this new generation LCD slate, it is quite simply "magic"! Write down your shopping lists, messages and appointments, ... then when you no longer need it, erase everything with a little click on the bin button and start again! So you can reuse it, again and again! Its magnetised rear side allows you to attach it to any metallic surface (very useful for the fridge, for example!). Plastic. Dim.: L. 22.7 x W.14.6 x H.0.5 cm. 8.5 inch screen (21 cm). Works with 1 CR2016 button cell battery, provided.
