Useless Box by MSRaynsford.co.uk
This is a wonderful battery operated novelty for those with a sense of humour. Flick the switch on the top of the box to the ON position. Immediately the box opens and a wooden finger comes out to push the switch back to the OFF position, before vanishing back into the box. A box that doesn’t want to be opened – how useless is that? The box, made out of laser cut wood, comes in kit form.
