Firework Phalanges is part of the 2021 Facebook VIP Group Trio - these 3 colours are exclusively for customers who are part of the Gallivanting Nails VIP Group on Facebook.
Firework Phalanges is a dark black linear holo. It was hard to capture the holo sparkle in photos due to the dark black base but it shows up well in sunlight.
Shown in 3 coats, with swatches from @swatchitpink
