Magnetic numbers & magnetic letters are used by teachers for different purposes and different needs.
We have sets of magnetic letters as small as 3/4", and as large as 6". Magnetic letters with straight tails, and with curved tails on the lower case y and t. Magnetic letters with smooth surfaces, and with ridges on the outside edge. Magnetic letters with red vowels and blue consonants, and sets with letters in six mixed colors.
Our magnetic letters are made out of molded plastic, and made from die-cut foam, so the entire letter is magnetic and won't slip even on a slippery wipe-off board.
