Argos have 20% off the Tomy Megasketcher, which was £12.99 and is now selling for £9.99. It's available in store on click and collect, but not for home delivery, and would make an excellent stocking filler or small gift for under £10.
I love these sketch pads of various types for long car journeys, or drawn out restaurant visits. They don't require batteries, ink or paper and they don't have anything that can make a mess. And you don't have to carry masses of supplies along with you either, because you can draw and redraw on the same surface time and again.
It has a magnetic drawing board with a special screen, and the pictures magically disappear with one sweep of the eraser. The pen that comes with it draws both thick and thin lines for greater options in drawing. The pen is attached so it wont get lost, and there are four shapes that work as stamps for added decorative fun.
