These are kits that can be purchased in bulk for classrooms, libraries, clubs, and other large groups. The price is heavily discounted. I'm a teacher myself, and know it's sometimes not cheap to bring cool projects into the classroom. I'm trying to help ya out here. Please order a minimum of 10.
After your purchase, please email me at (firstname.lastname@example.org) if you'd like me to record a quick video encouraging your group and saying hello. Thanks!!
