The Galt Water Magic – Water Magic 123 is a fun creative activity. It is a great way to develop writing skills and learn the alphabet with 6 reusable boards. Use the water pen to form the numbers 1 to 20 following the dotted lines and see the coloured numbers appear. Then reveal the picture with the corresponding number of items and the number word. The numbers, pictures and words will appear and later disappear over and over again.There’s no mess, because there’s no ink. The 8” x 6” pad includes six reusable pages and comes with a thick refillable water pen. This reusable activity tablet is suitable for use by children 3 years and older.
