- This title features a special glittered UV border which replaces the printed black line. This helps young children develop their motor skills and gives a more tactile guide to staying in the lines, making it easier and more satisfying for them to produce. Winnie-the-Pooh, this bumpy line book is a great way to practice your colouring skills! With bumpy edges to help you stay in the lines and make lots of colourful pictures of Pooh and his friends.
