Great for no spills [SEP] These are great little silicone nail polish holders.  Because they are soft they can fit most polishes.  Depending on the shape of the bottle some work better than others.  I even use it not just to hold my polish so I don't spill it.  I also can tilt the polish bottle far enough so when you are down to the end of the bottle, it is easier to get what polish is left out.  I would recommend these polish bottle holders.
