From the release:
Today we look at a new defensive wall system to complement the Laser Defense Walls. This time around we have a new smaller version based on the idea of a deploy-able shielding system similar to the one in the video game Halo. The idea was to create a man portable shield that could be quickly deployed and fit squarely in the thigh tech world of Sci-Fi.
This kit includes 8 sections of shielding in 2 different sizes, 4-2" and 4-5". Each kit gives 28" of cover and is available in, clear, frosted white, dark grey and the florescent colors of green, orange, blue and pink.
