Zoya Happi is from their 2010 Reverie collection. I ordered this over a year ago and I never tried it on before so I decided to try to today. Happi is a bubblegum pink color with a golden sheen to it, which is pretty subtle.
The first coat made it seem like it was going to be sheer because the polish itself was kind of runny, but the second coat covered pretty much the whole nail. Since this is a light color, you would be able to see the nail if you put your nails over a light or reach it above the sunlight to see it.
