Crayola Alien & Monsters Coloring Set

I was quite excited to try these markers. So much so that I didn't realize they are basically just glow sticks and have a limited life. Two of us set out to color the 5 pictures out came with based on the four working hours the package said we had. Considering the detail in the pictures for two adults coloring, we would have liked a finer tip to accomplish it, but that is minor in comparison to color and glow quality. My biggest complaints are these... we opened this to color and started immediately. After 30 minutes of two adults coloring with a purpose, all but one marker was too dry to use. One of which was barely used and was virtually trash from the beginning (red). I cannot figure out how to turn off the night photo enhancement on my phone camera so the colors in the picture are much better than in person for the glow with red and blue. The red and blue are barely perceptible, i can tell something is happening but not what color by eye... this is probably to do with the red starting very dry. Green was the next driest and next to dry out despite being brighter than the blue (it was basically invisible). Yellow and orange were the only two good colors. When we viewed the images in the light we were able to see just how faint and splotchy the color was. Considering the glow was the goal, I could have ignored it if the glow was better. Mind you despite us working quick within the 4 working hours of glow, and completing the images in approximately 30 minutes, the images were invisible in the dark an hour after that. We got less than 90 minutes of that 4 hours and were only able to use 4 of the 5 color sheets and 0/2 blanks before all of the markers dried out. Not sure if this was just a defective pack, but I know I'll never buy or recommend this set and will be more warry if new types of crayola markers in the future.
