It only took one coat to get completely opacity, the formular is rather thick but easy to apply. To be honest: My search for the perfect red holo hasn't ended, yet. Most holos disappoint me as the holo effect is invisible in most lightings, 621 being no exception.While it is nice & sparkly I still wish for a stronger holo effect!
Ozotic Pro is an Australian brand. I got my polishes through a swap, but you can also order them here . They offer worldwide shipping.
