Heavy duty plastic rubbing plates (130x130mm) with raised highlighted surfaces for easy rubbing. Suitable for use with crayons and pencils. Kinder Rubs are excellent for developing bilateral hand skills as it's really important for the 'helper hand' to hold the plate firmly to get a good picture. They are also good for children who need to learn to increase or decrease their pressure with the pencil or crayon.
