The Sandpaper Letters in lower case print are presented in the traditional colours of blue for vowels and pink for consonants.  The letters themselves are fine-grit sandpaper on painted hardboard for a durable, long-lasting finish.  The set includes an extra "y" in blue (twenty-seven letters in all) for instances where y is used as a vowel.  Short letters, such as "a", "c" and "n" measure 16 x 11 cm (about 6" x 4"), while tall letters such as "k", "b" and "l" measure 19 x 14 cm (about 7.5" x 5.5").  The set includes a wooden box for display and storage.
