This is a POP (Point of Purchase) display for Prismacolor Markers. It holds seven tester markers in a half-circle base, fanning them out like a rainbow, and a small sketch pad on the base. The purpose of the display is to entice customers to sample the markers, thus encouraging them to make an impulse purchase.
The dominant color of the display is a glossy black for two reasons:
1) to maintain a consistent look throughout its branding and
2) to discourage customers from testing the markers on the display
(as is often done with most other marker displays).
