H&M Hello Kitty Pink Summer which is the pink sister polish to this one. This one is called Corall Summer (not sure why it's spelt like that)!
As with the pink version, this polish is absolutely amazing. It ticks all my boxes which is always a bonus for a cheap polish (£2.99). The formula is excellent, it's opaque in 1 coat (but the pictures have 2 of course) and drying time is faster than the average polish. It's such a pretty shade of blue as well and look how cute the bottle is - like Ciate but without the bow!
