Butter London- Shag

This is the third and final Butter London polish I got for my birthday last year. It is part of the core collection (3-free) of Butter London, not the Rock Your Colour expansions they have been doing with color cosmetics lately.
The color is a warm copper tone with a metallic foil finish. I currently do not have any close dupes for this color.
The finish is absolutely beautiful. The glitter or glass particulates (probably glass) don't leave any topography on the nail, drying completely flat and smooth before topcoat application. The formula is thin and easy to control, becoming opaque in two coats.
My only con with this polish is also with the line in general; the package quality is not what one would expect from a "prestige" cosmetics brand. The cap is in two parts and come apart without much effort and the brush is very small and a little bit flimsy. Maybe they make the bottles a little cheaply to allocate more budget to the quality of the formula. That is my best guess because the quality of these formulas is definitely worth the price.
