Today I've got one of the Layla Bubble Effect polishes to share with you- this is Black Forest, a polish very similar to OPI's Black Spotted lacquer (which was exclusive to Europe, if I understand correctly). In terms of application, I applied this as I would a shatter topcoat: I used one medium coat, applied it quickly and evenly, and then I stopped fussing with it. The end result was this oil-on-water kind of effect. The base colour is SpaRitual Quietness.
I also layered this over Man Glaze's Butt Taco (oh, that name...) which I think provided a more striking effect.
What do you think of Layla Bubble Effect in Black Forest? Think it would quell any lemming for the hard-to-procure OPI Black Spotted? If so, and you're wondering where you can order it, you can find it at Nail Polish Canada, which is where I ordered mine from.
