Barry M black multi glitter is exactly what the name says it's a black shade with small holo glitter. The shade is quite pigmented and looks gorgeous under a glossy top coat. For the pictures I applied 2 coats but you can get away with just one coat has the polish is very pigmented. I was not able to catch the holo glitters in my pictures but this polish remind me a lot of swatches I saw from Zoya Storm.
You can find it in Superdrug, Boots, Barry M website for £2.99 for 10ml
