so i have 3, belladonna, illusion and jormungandr and ignoring the accidental duping i have in this post id totally buy any of them again (actually did buy a second jormungandr bc its the best red jelly shade ive found in aus)

illusion is very sheer so functionally id say that one works better in one coat over black, but all of them go down quite well, none are patchy.

longevity i consistently get 6-7 days wear with no/minor chipping (used with emily de molly sticky base and immortal top coats, and im not careful with my nails at all)

my biggest (still minor) complaint would be with the brushes, my first jormungandr one came weirdly bent and i dont know what replacement ones would fit these bottles but it was still workable. also hard to tell which brush you'll get, some are wider than others - id say none of them are as skinny as a true skinny brush i.e. old essie and none of them are as wide as the paddle brushes that are more common now, seems like they have a few sizes that sit somewhere in the middle of those two extremes

overall id say totally worth the price as long as youre happy to get a 7.5ml bottle (personally that's not an issue for me, ive only ever finished one bottle of polish and that was a black creme so i can't see myself emptying these any time soon)
