Dear Sir or Madam,
Everyone has experience of wiping blackboard in schooldays, that’s quite tiring when we use the eraser cleaning it each time. The blackboard and erasers have basic functions on teaching, but the shortcoming is chalk dust produced, it's not a good idea for teaching quality.
Especially the blackboard always cleaned by teachers and students, it ‘s harmful to health even more. And above all, too much lime which enters the lung to make teachers get more risk of chronic lung diseases, students suffer the dust as well.
The improved product, the white board, the greatest shortcoming will produce the particular smell, volatility, damages teachers' health too. Besides, marker pens often need to refill ink. It’s not a economical method of education.
To improve our learning environment, we design “Auto-Clean” Eraser.
Attached please find our DM for your kindly reference. Please contact us
if there are any questions or interests with our product.
We thank you for your attention and look forward to hearing from you.
We hope to be able to build up a close relationship with you to our mutual benefit. We can be contacted either by fax or e-mail.
Sincerely yours,
Debbie Ma
