Another exciting ebay buy is China Glaze Let's Do It In 3D from their Kaleidoscope collection. I paid around £7.99 and a couple of pounds for postage. Overall, a good price for a discontinued holographic polish.
I will let the pictures do the talking: these are three coats.
My holographic collection is slowly but surely getting bigger. I am always keeping my eyes open for them. What is your favourite holographic polish?
