One polish I did not get as much use out of this year as I had expected was Barry m Red glitter. It's a beautiful jam packed red glitter. It is opaque in 2 coats and once you add on a topcoat it looks so pretty. I tend to use it more so around Christmas both as a full manicure and in nail art. I only used it a handful of times but it's still a great glitter.
I've had this bottle for a good year or two now and it's still in great shape. It hasn't thickened at all. It's the only reg glitter I have come across in shops too so I'm delighted it has lasted so long.
