Opi is always great but this bottle must be old or has been impacted by environmental conditions. It streaked and clumped a little wen dry. Can be resolved but shouldn't have to for a new bottle. Never have I experienced this with opi before! It seemed like a cheap enamel...bottle wasn't sealed in plastic/stickers like they usually are...is it really opi?? or has opi changed its products??
