I purchased a bottle of Technic ‘Carnival’ the other day. It’s apparently a very good dupe of OPI Rainbow Connection only with a much smaller price tag (I paid less than £2.50 delivered from Amazon). I was going to use it for some glitter tips but when it arrived I though it was perfect to do a glitter sandwich manicure. As the name suggests the glitter polish is basically sandwiched between layers of nail polish.
Base: Chanel Ballerina
Middle: Technic Carnival
Top: Chanel Ballerina (two coats as it’s very sheer)
Verdict: Another very simple manicure. If you can paint your nails reasonably neatly then you could try this with whatever ‘bread and fillings’ you have in your collection. I shall be trying it with some brighter colours in the near future.
