Punyopunyo Aquarium Color Ink 6 Colors Set of 12 New, Unopened Red, Light Blue, Glow-in-the-Dark, Black, Purple, Orange 2 of each color Includes 2 glow-in-the-dark bottles that shine in the dark. Since this is a new, unopened item, the contents have not been confirmed. Shaking to mix should solve any issues, but there is a possibility the liquid has separated. The glow-in-the-dark color is especially prone to separation due to its properties. Please understand this before purchasing. I recently used a similar item purchased at the same time, and it worked without any problems. I am also selling a solidifying powder. Please refrain from price negotiations.
