These are 2 Fisher-Price Think & Learn Code-a-Pillar, with 11 rear segments, between the two. The pillars have both been tested, and they both work excellently. They are overall in Good condition, one of the pillar's Fisher Price logo on the side has some fading and marks to it, otherwise they are both in great shape. They both run on 4 AA batteries each, these batteries are not included to keep the weight under. This comes with 2 main Code-a-Pillar units and 11 rear segments, that can be swapped around and placed in any order. When socketed in and the button on the back is pressed, the pillar runs through the order of the segments and then plays them out one by one. The whole time its moving and processing the segment it lights up, flashes, plays music and sounds, so its very interactive and attention grabbing. Its comes from a smoke free and pet free home, and will be packaged and shipped with great care.
