How to use this letter set?
children learn to trace the letters and practise the pronunciation.
after children know how to trace the letters,they can put a letter on the left frame,put sand on the right frame(It is forbidden to send powder and soil by international mail ,so we do not sell sand, you can prepare it yourself),write the letters on sand tray.
the left frame is a bit bigger than the letter for children take it out or put in easily.
