Subject:         Items for Science Classes - New
Date: December 24, 2013 at 6:49 pm PST

I have several items I purchased for high school sciences but never used
them because we sent our kids to our community college for these
courses. I am selling the items at half the cost I paid. They are
items that are needed for Bob Jones and Abeka science courses.

All items were never used, and they are clean, smoke free, and still in
new condition. I can e-mail you pictures if you want me to.

Shipping will be extra. I will accept Paypal, a check, or money order.
