Color-coded plastic strips attach to the plain Snap Cap for a classroom visual of the four basic forms. Using this hands-on teaching aid, students will be able to examine the length arrangements of each form structure when the strips are held at a normal projection and compare the surface textures when strips are at a natural fall. Each order contains four sets of projection strips: solid, uniform, graduated and increase forms. Set Includes: Headform, Cap with magnetic buttons, Uniform projection strips, Solid projection strips, Graduated projection strips, Increase projection strips.
