Teacher, do you like what you see?

If you need to gather funds, I can send you a quote for starters. Once the funds and your unit are both ready, your box ships. The enclosed paper invoice won't even be due for 30 days.  That will give you and your students the chance to see what this is all about. Then, $900.00 can be submitted through a PayPal link or with an old-fashioned check-in-the-mail.

You are going to love this thing!
