I also received an email from Lacquerous regarding their polish sharing program. It looked appealing to me, but when I started reading the fine details, I became a little concerned. The "sharing" part really concerns me. What if you pay your $18 and end up receiving a 1/4 full bottle of polish that's thick and unusable? As far as bacteria, fungus, or other microbes not being able to grow in polish, I don't support that study (whatever company did the study) at all. Bacteria lives all around us. Different types of bacteria can grow in ANY condition. I bet if I were to take a used bottle of polish and run a microbiology test, some bacteria would be present. Although, this said bacteria may not necessarily cause harm. When I worked as a nail tech for 12 years, I separated the nail polish from the toenail polish. Anytime I SUSPECTED nail fungus, the base coat, nail polish color, AND top coat got tossed (even if it was brand new)! Fungus is so easy to get BUT hard to rid of. Lastly, I just don't think Lacquerous thought this through enough. Maybe, if they went back to the drawing board, they could turn this around. Just my $.02
