Almost impossible to find 'toys' for her to help her with her strength and to keep her occupied (either the products available are for dementia sufferers, or for children). This nuts / bolts are brilliant, keep her occupied, and require her to use both her hands to undo / redo each nut + bolt. Review: Seriously impressed with these! - Really lovely set of nuts and bolts STEM toys, chunky, excellent for little fingers offering varying size if each colour, which I had not realised. I think we will have many an enjoyable time playing, colour and shape sorting, stacking and screwing them on and off too. Got them for £9.99, so didn't hesitate, not sure how often they are this price, but having found and got them, I am more than happy. They come in a zippy bag for storage, but also easy to use the box again, or another container. ## Features - Warning:Not suitable for children under 3 years.
