Pro 10 Violetta
You'll see that it's located in an album called Purple Shimmer. Click on the word Shimmer. You get 50 pages of purple shimmers. Yes, 50! You work your way through the pages and I notice a polish on the second page that isn't a dupe but I quite like it and I know it goes for about a squid on amazon. It's Pro 10 Violetta. Then there are plenty of OPI. Maybe they're discontinued but there's always ebay.
I'm mad for Illamasqua Rampage but I'm not paying Illamasqua prices. I do a nailgal search and find it under green creme so I click on creme. Only 25 pages this time and not many possible dupes but I do like this.
Not a dupe but I like it. So that's nailgal. If my pix were good I'd upload them. If you DO contribute to nailgal I thank you because it's a great resource. I'm a member so it's OK to copy/paste their pix as long as I give the correct attribution. You can spend hours looking through those photos. If you are a good photographer and you don't already upload to nailgal then maybe consider it?
