Hey there :D
I was in the mood for some holos and recently bought a bottle of QT. QT is a magenta holo and part of the OMG series by China Glaze. Sadly, they are discontinued but you may be lucky to find some of them at etailers.
I've already shown you DV8 here. QT and DV8 were opaque in two coats and I didn't had any problems with either polish. I stamped with the black Konad Princess polish and Image Plate HB24 (a coffee/tea-themed image plate).
