The nature of any polish that contains glitter is that every second the lid is off the bottle the ratio of liquid to glitter is changing, i.e, it becomes MORE glittery with every use as the solvents evaporate. I went through many bottles of Ruby Ritz last year and this was true from bottle to bottle, every time I opened a new one it seemed 'less glittery', because it was! There was more liquid in the bottle when it was first opened. Once the bottle was about half way it was more glittery and the last manicure from the bottle was the glitziest of all!
Honestly, I am not trying to call you ladies liars, and please if you genuinely feel you have a faulty product you must contact S2 or the distributor partner you bought it from.
Every bottle of Ruby Ritz I have used so far this year has been exactly the same as last year, more liquid at first, a higher ratio of glitter use by use.
This is the nature of glittery polish. Every polish containing glitter that I have owned in the last 15 years has been like this.
