These Unicorn pens are something else. They are ALL different, everyone. There are 6 different colour pens each with a different colour of light, Some are pink, green, white and blue, some even are rainbow and rotate different colours! Not one colour pen has the same colour light. They are totally random! So this listing is random! They might be random but they are SO CUTE! They each have a little glass ball that very brightly lights up with a laser etched unicorn inside. They are just beautiful to write with though. Very dark black gel ink that flows beautifully onto paper and never bleeds. They also have "Dream like a Unicorn" on the side of each one.
